i80186/188 peripherals to fail to be properly mapped into memory space. [crazyc, Lord Nightmare]

instructions whose execution time is normally indefinite. When this happens, a special message may be printed to the debug console stating the location of the last actual instruction executed before the wait (if there was one).
Note that since the callback ignores the current value of the program counter, this special type of debugger break cannot be entered through breakpoints or instruction stepping commands. The callback also leaves no effect on PC history tracking or trace logs.

Read callbacks now need a default return value supplied at construction.
Replaced isnull() with isunset() which tells you if the callback wasn't
configured rather than whether it isn't safe to call.
Enabled validation of device callbacks (it seems it was disabled at some
point, probably accidentally).
Device callbacks and object finders now implement the same interface for
resolution.

Uses decay rules, so if a delegate returns a reference and you want to
supply a referene to an object you don't want copied as the default
result, remember to use std::ref.
Updated a few devices to use resolve_safe on device delegates to
streamline code.

members. (#9788)
Primarily, this removes device_t::device_timer, device_t::timer_set,
device_t::synchronize, device_t::timer_expired, and device_timer_id.
Use of device_timer often resulted in unnecessary trampolining in
addition to switch/case overhead on a driver/device level, and
additional logic to manage delegated vs. ID-based timers on a core
level. In the worst cases, devices were performing a switch/case with
only one valid case.
device_scheduler::timer_set is marked deprecated as the only remaining
direct uses are via the Lua engine and a few drivers that need
refactoring anyway. The remaining uses occur via
device_scheduler::synchronize.
As a middle ground between the extremely short timer_alloc() and the
extremely long
machine().scheduler().timer_alloc(timer_expired_delegate(FUNC(widget_device::contoso_tick), this)),
a helper function in device_t has been added which can be invoked with
the following syntax:
timer_alloc(FUNC(widget_device::contoso_tick), this)

fundamental change to show device delegates are configured.
Device delegates are now aware of the current device during
configuration and will resolve string tags relative to it. This means
that device delegates need a device to be supplied on construction so
they can find the machine configuration object. There's a
one-dimensional array helper to make it easier to construct arrays of
device delegates with the same owner. (I didn't make an n-dimensional
one because I didn't hit a use case, but it would be a simple addition.)
There's no more bind_relative_to member - just call resolve() like you
would for a devcb. There's also no need to cast nullptr when creating a
late bind device delegate. The flip side is that for an overloaded or
non-capturing lambda you'll need to cast to the desired type.
There is one less conditional branch in the hot path for calls for
delegates bound to a function pointer of member function pointer. This
comes at the cost of one additional unconditional branch in the hot
path for calls to delegates bound to functoids (lambdas, functions that
don't take an object reference, other callable objects). This applies
to all delegates, not just device delegates.
Address spaces will now print an error message if a late bind error is
encountered while installing a handler. This will give the range and
address range, hopefully making it easier to guess which memory map is
faulty.
For the simple case of allowing a device_delegate member to be
configured, use a member like this:
template <typename... T> void set_foo(T &&...args) { m_foo_cb.set(std::forward<T>(args)...); }
For a case where different delegates need to be used depending on the
function signature, see src/emu/screen.h (the screen update function
setters).
Device delegates now take a target specification and function pointer.
The target may be:
* Target omitted, implying the current device being configured. This
can only be used during configuration. It will work as long as the
current device is not removed/replaced.
* A tag string relative to the current device being configured. This
can only be used during configuration. It will not be callable until
.resolve() is called. It will work as long as the current device is
not removed/replaced.
* A device finder (required_device/optional_device). The delegate will
late bind to the current target of the device finder. It will not
be callable until .resolve() is called. It will work properly if the
target device is replaced, as long as the device finder's base object
isn't removed/replaced.
* A reference to an object. It will be callable immediately. It will
work as long as the target object is not removed/replaced.
The target types and restrictions are pretty similar to what you already
have on object finders and devcb, so it shouldn't cause any surprises.
Note that dereferencing a device finder will changes the effect. To
illustrate this:
...
required_device<some_device> m_dev;
...
m_dev(*this, "dev")
...
// will late bind to "dev" relative to *this
// will work if "dev" hasn't been created yet or is replaced later
// won't work if *this is removed/replaced
// won't be callable until resolve() is called
cb1.set(m_dev, FUNC(some_device::w));
...
// will bind to current target of m_dev
// will not work if m_dev is not resolved
// will not work if "dev" is replaced later
// will be callable immediately
cb2.set(*m_dev, FUNC(some_device::w));
...
The order of the target and name has been reversed for functoids
(lambdas and other callable objects). This allows the NAME macro to
be used on lambdas and functoids. For example:
foo.set_something(NAME([this] (u8 data) { m_something = data; }));
I realise the diagnostic messages get ugly if you use NAME on a large
lambda. You can still give a literal name, you just have to place it
after the lambda rather than before. This is uglier, but it's
intentional. I'm trying to drive developers away from a certain style.
While it's nice that you can put half the driver code in the memory map,
it detracts from readability. It's hard to visualise the memory range
mappings if the memory map functions are punctuated by large lambdas.
There's also slightly higher overhead for calling a delegate bound to a
functoid.
If the code is prettier for trivial lambdas but uglier for non-trivial
lambdas in address maps, it will hopefully steer people away from
putting non-trivial lambdas in memory maps.
There were some devices that were converted from using plain delegates
without adding bind_relative_to calls. I fixed some of them (e.g.
LaserDisc) but I probably missed some. These will likely crash on
unresolved delegate calls.
There are some devices that reset delegates at configuration complete or
start time, preventing them from being set up during configuration (e.g.
src/devices/video/ppu2c0x.cpp and src/devices/machine/68307.cpp). This
goes against the design principles of how device delegates should be
used, but I didn't change them because I don't trust myself to find all
the places they're used.
I've definitely broken some stuff with this (I know about asterix), so
report issues and bear with me until I get it all fixed.

This effectively reverts b380514764cf857469bae61c11143a19f79a74c5 and
c24473ddff715ecec2e258a6eb38960cf8c8e98e, restoring the state at

Before pushing, please check that what you're about to push is sane.
Check your local commit log and ensure there isn't anything out-of-place
before pushing to mainline. When things like this happen, it wastes
everyone's time. I really don't need this in a week when real work™ is
busting my balls and I'm behind where I want to be with preparing for
MAME release.

Connected SMIOC DMA to 68k
* SMIOC now reading bytes for serial from the 68k memory space successfully.

68k now running in lockstep with SMIOC for serial
* 68k now uses actual SMIOC as source of SMIOC status, so it waits for the SMIOC to complete commands before continuing.
* SMIOC DMA controllers now being asked to move bytes around
* "write character" (4100) commands to SMIOC are now completing and resulting in correct status being written and sent back to the 68k
* Every now and then the SMIOC stalls for a bit, it seems to be due to spending some time trying to communicate with the 8051 CPU (used to communicate with another cpu on the serial breakout box) that is not currently present in the emulated device.
Next Steps:
* We're going to move the terminal from the r9751 into the SMIOC, and hook it up to the DMA controllers as a hacky temporary solution.
* We need to emulate the 5xxxx memory range in SMIOC to proxy data to/from the 68k memory
* Then we'll start work on emulating the octal uart properly and hooking it up to RS232 channels.

Tinkering to get SMIOC further along
1) Enable 188 cpu to advance DMA immediatley if DRQ is held high when source synchronous DMA is started (It's not clear whether the DMA actually works this way yet)
2) Retrigger the DMA DRQ when a memory access is made to the DMA window (future work needed to proxy the reads/writes to the 68k's main memory) This is needed to support multibyte DMA reads/writes to the 68k window.
3) Reverse the bytes in the status register (based on current incomplete understanding of how this is encoded)
4) Connect the status register back to the r9751 on SMIOC status read
Current state: SMIOC's main board DMA state machine now completes the DMA transfer from the main board (With incorrect data), but we are still getting stuck.
Next steps: SMIOC is now hanging waiting on DMA to UART to complete, we need to implement some emulation of the UART and its connections to the surrounding 16 dma channels in order to make progress.

Experimenting with SMIOC emulation
* Partial fixes for line state issues with persistent line values
When the AM9517 DMA controller mode is updated to change the polarity of DACK/DREQ, it doesn't update the DACK line values / request values (respectively).
This fixes this issue for one of the emulated devices in the file, but the other device has the same problem.
* Add skeleton of SCC2698B UART device
* Early progress on emulating SCC2698B Octal UART
Core structure for IO lines and writing registers is in place.
* Update address maps to new format.
* SCC2698b: Add tx/rx, baud rate generation
* Emulation improvements for scc2698b device
* MPP output pins emulated
* Improved logging for baud rate changes
* Channel configuration emulated
* Support for TX/RX Enable
* Started integrating new features into SMIOC
* Minor progress on the path to enabling new UART for SMIOC
* Resolved code issues related to upstream changes
* Working around an apparent problem with callbacks on sub-device devices
* Terminal added for serial port attached to SCC2698B UART.
* Things compile and seem to work.
* SMIOC: Serial is now outputting correctly through emulated SMIOC
Some glitches to work out, but this is nearly ready.
* AM9517a should not forget about input line status on master reset.
* Disable tracing
* SMIOC: Improving diagnostics and making some progress on the emulation
* Revised tracing in SMIOC and SCC2698B
* Improved tracing approach in r9751
* Minor progress towards working SMIOC emulation.
* [R9751] Update drivers to new code patterns after rebase
Rebased on latest mame, Fixed a few issues and updated the callback code patterns based on recent changes in devcb
* [R9751] Improve logging, fix interrupt race
Serial no longer drops output characters
* [R9751] Working on SMIOC emulation
Improved SMIOC emulation accuracy, Made some progress in getting through the disktool initialization sequence, but we are still hitting a problem - It looks like disktool should be resetting the SMIOC board when it starts, but the mechanism for this has not been found.
* [R9751] Improve tracing for system board registers
* [R9751] Improve SMIOC emulation
Still having some trouble with SMIOC but this seems to be an improvement.
SMIOC is now waiting for a status to be read before applying a new status, and mandatory parameter read logic is in place.
* [R9751] Incremental emulation improvements
the SMIOC failure was understood and fixed, and a new approach to getting the hardware to bootstrap correctly was implemented - Still having some problems with it though.
* [R9751] Fixed emulation issues
* Disktool now boots to the console
* UART receive only partly working, I don't think it's fully connected yet.
* [R9751] Further progress on SMIOC emulation
* Figured out the missing command parameter interface to the SMIOC board
* Still blocked because the SMIOC interface to the breakout board through an onboard 8051 is not emulated and the disktool software depends on properties coming from it.
* [R9751] Terminal is fully working for disktool
* Improved the emulation of the 80188 to 451 connection in order to reliably set a status bit disktool depends on.
* [R9751] Fix build after rebase
* [R9751] Cleanup, tracing improvements
* Remove second emulated terminal - SMIOC is now stable enough to run the terminal.
* Remove older and unnecessary emulation/tracing code
* r9751: Fix compile error and modify copyright holders

- Make read_byte/word and write_byte/word overridable virtual functions (80186 MMU probably will need to override this in the future)
- Make fetch_op an alias for fetch (implementations were identical already)
- Remove sreg argument from read_byte/word and write_byte/word (it was almost always m_easeg as set by calc_addr, sometimes with dubious evaluation order)
- Restrict logic for separating address spaces for CS/ES/SS accesses to 8086/8088 (later x86 models do not broadcast the descriptors)
- Encapsulate m_e16 within the only function that used it

significant change, so please pay attention.
The core changes are:
* Short name, full name and source file are no longer members of device_t, they are part of the device type
* MACHINE_COFIG_START no longer needs a driver class
* MACHINE_CONFIG_DERIVED_CLASS is no longer necessary
* Specify the state class you want in the GAME/COMP/CONS line
* The compiler will work out the base class where the driver init member is declared
* There is one static device type object per driver rather than one per machine configuration
Use DECLARE_DEVICE_TYPE or DECLARE_DEVICE_TYPE_NS to declare device type.
* DECLARE_DEVICE_TYPE forward-declares teh device type and class, and declares extern object finders.
* DECLARE_DEVICE_TYPE_NS is for devices classes in namespaces - it doesn't forward-declare the device type.
Use DEFINE_DEVICE_TYPE or DEFINE_DEVICE_TYPE_NS to define device types.
* These macros declare storage for the static data, and instantiate the device type and device finder templates.
The rest of the changes are mostly just moving stuff out of headers that shouldn't be there, renaming stuff for consistency, and scoping stuff down where appropriate.
Things I've actually messed with substantially:
* More descriptive names for a lot of devices
* Untangled the fantasy sound from the driver state, which necessitates breaking up sound/flip writes
* Changed DECO BSMT2000 ready callback into a device delegate
* Untangled Microprose 3D noise from driver state
* Used object finders for CoCo multipak, KC85 D002, and Irem sound subdevices
* Started to get TI-99 stuff out of the TI-990 directory and arrange bus devices properly
* Started to break out common parts of Samsung ARM SoC devices
* Turned some of FM, SID, SCSP DSP, EPIC12 and Voodoo cores into something resmbling C++
* Tried to make Z180 table allocation/setup a bit safer
* Converted generic keyboard/terminal to not use WRITE8 - space/offset aren't relevant
* Dynamically allocate generic terminal buffer so derived devices (e.g. teleprinter) can specify size
* Imporved encapsulation of Z80DART channels
* Refactored the SPC7110 bit table generator loop to make it more readable
* Added wrappers for SNES PPU operations so members can be made protected
* Factored out some boilerplate for YM chips with PSG
* toaplan2 gfx
* stic/intv resolution
* Video System video
* Out Run/Y-board sprite alignment
* GIC video hookup
* Amstrad CPC ROM box members
* IQ151 ROM cart region
* MSX cart IRQ callback resolution time
* SMS passthrough control devices starting subslots
I've smoke-tested several drivers, but I've probably missed something. Things I've missed will likely blow up spectacularly with failure to bind errors and the like. Let me know if there's more subtle breakage (could have happened in FM or Voodoo).
And can everyone please, please try to keep stuff clean. In particular, please stop polluting the global namespace. Keep things out of headers that don't need to be there, and use things that can be scoped down rather than macros.
It feels like an uphill battle trying to get this stuff under control while more of it's added.

* Make device_creator a variable template and get rid of the ampersands
* Remove screen.h and speaker.h from emu.h and add where necessary
* Centralise instantiations of screen and speaker finder templates
* Add/standardise #include guards in many hearers
* Remove many redundant #includes
* Order #includesr to help catch headers that can't be #included alone
(nw) This changes #include order to be prefix, unit header if applicable
then other stuff roughly in order from most dependent to least dependent
library. This helps catch headers that don't #include things that they
use.
