This effectively reverts b380514764cf857469bae61c11143a19f79a74c5 and
c24473ddff715ecec2e258a6eb38960cf8c8e98e, restoring the state at
598cd5227223c3b04ca31f0dbc1981256d9ea3ff.
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.

* Add per-language compiler flag options to help with exotic setups
* Get rid of a potention buffer overrun in NuBus image card
* CHAR_WIDTH and LONG_WIDTH are preprocessor macros in limits.h with glibc if __GLIBC_USE (IEC_60559_BFP_EXT) is enabled - avoid using them as names
* Make formats/upd765_dsk.h slightly safer with defualt initialisers for key format members
* Don't rely on random BSS data being zero in imagedev/floppy.cpp

There are multiple issues with the current device callbacks:
* They always dispatch through a pointer-to-member
* Chained callbacks are a linked list so the branch unit can't predict the early
* There's a runtime decision made on the left/right shift direction
* There are runtime NULL checks on various objects
* Binding a lambda isn't practical
* Arbitrary transformations are not supported
* When chaining callbacks it isn't clear what the MCFG_DEVCB_ modifiers apply to
* It isn't possible to just append to a callback in derived configuration
* The macros need a magic, hidden local called devcb
* Moving code that uses the magic locals around is error-prone
* Writing the MCFG_ macros to make a device usable is a pain
* You can't discover applicable MCFG_ macros with intellisense
* Macros are not scoped
* Using an inappropriate macro isn't detected at compile time
* Lots of other things
This changeset overcomes the biggest obstacle to remving MCFG_ macros
altogether. Essentially, to allow a devcb to be configured, call
.bind() and expose the result (a bind target for the callback). Bind
target methods starting with "set" repace the current callbacks; methods
starting with "append" append to them. You can't reconfigure a callback
after resolving it. There's no need to use a macro matching the
handler signatures - use FUNC for everything. Current device is implied
if no tag/finder is supplied (no need for explicit this).
Lambdas are supported, and the memory space and offset are optional.
These kinds of things work:
* .read_cb().set([this] () { return something; });
* .read_cb().set([this] (offs_t offset) { return ~offset; });
* .write_cb().set([this] (offs_t offset, u8 data) { m_array[offset] = data; });
* .write_cb().set([this] (int state) { some_var = state; });
Arbitrary transforms are allowed, and they can modify offset/mask for example:
* .read_cb().set(FUNC(my_state::handler)).transform([] (u8 data) { return bitswap<4>(data, 1, 3, 0, 2); });
* .read_cb().set(m_dev, FUNC(some_device::member)).transform([] (offs_t &offset, u8 data) { offset ^= 3; return data; });
It's possible to stack arbitrary transforms, at the cost of compile
time (the whole transform stack gets inlined at compile time). Shifts
count as an arbitrary transform, but mask/exor does not.
Order of mask/shift/exor now matters. Modifications are applied in the
specified order. These are NOT EQUIVALENT:
* .read_cb().set(FUNC(my_state::handler)).mask(0x06).lshift(2);
* .read_cb().set(FUNC(my_state::handler)).lshift(2).mask(0x06);
The bit helper no longer reverses its behaviour for read callbacks, and
I/O ports are no longer aware of the field mask. Binding a read
callback to no-op is not supported - specify a constant. The GND and
VCC aliases have been removed intentionally - they're TTL-centric, and
were already being abused.
Other quirks have been preserved, including write logger only logging
when the data is non-zero (quite unhelpful in many of the cases where
it's used). Legacy syntax is still supported for simple cases, but will
be phased out. New devices should not have MCFG_ macros.
I don't think I've missed any fundamental issues, but if I've broken
something, let me know.

This reverts commit 3c144c5b48a340bb796e2b311c36588a7e75f48d.
Returning attotime::never from get_next_transition when there
eventually is going to be transitions without any externally imposed
state change is incorrect.

* Get rid of implicit prefix for GFX decode names and prefix them all
* Get rid of special macro for adding GFXDECODE in favour of constructor
* Make empty GFX decode a static member of interface
* Allow palette to be specified to GFXDECODE as a device finder
* Removed diserial.h from emu.h as it's used relatively infrequently
Also fix darkseal and vaportra propely. The palette device
automatically attaches itself to a share with matching tag. The correct
solution here is to rename one or the other out of the way, since it was
never attached to a share before.

Start replacing special device macros with additional constructors,
starting with ISA, INTELLEC 4 and RS-232 buses.
Allow an object finder to take on the target of another object finder.
(For a combination of the previous two things in action, see either the
INTELLEC 4 driver, or the Apple 2 PC Exporter card. Also check out
looping over a device finder array to instantiate devices in some
places. Lots of things no longer need to pass tags around.)
Start supplying default clocks for things that have a standard clock or
have all clocks internal.
Eliminate the separate DEV versions of the DEVCB_ macros. Previously,
the plain versions were a shortcut for DEVICE_SELF as the target. You
can now supply a string tag (relative to current device being
configured), an object finder (takes on the base and relative tag), or
a reference to a device/interface (only do this if you know the device
won't be replaced out from under it, but that's a safe assumption for
your subdevices). In almost all cases, you can get the effect you want
by supplying *this as the target.
Eliminate sound and CPU versions of macros. They serve no useful
purpose, provide no extra checks, make error messages longer, add
indirection, and mislead newbies into thinking there's a difference.
Remove a lot of now-unnecessary ":" prefixes binding things relative to
machine root.
Clean up some miscellaneous rot.
Examples of new functionality in use in (some more subtle than others):
* src/mame/drivers/intellec4.cpp
* src/mame/drivers/tranz330.cpp
* src/mame/drivers/osboren1.cpp
* src/mame/drivers/zorba.cpp
* src/mame/devices/smioc.cpp

* src/devices/bus/isa/isa.h
* src/devices/bus/isa/isa.h

finder. This works outside machine configuration context so the
workarounds in ATA HLE and MSX slots are no longer necessary. It also
allows reduction in tag repetition in machine configuration (see
converted osborne1.cpp, zorba.cpp or the more extreme tranz330.cpp).
Allow reimagined device instantiation to take a device finder based on
current device being configured to reduce repetition (see tranz330.cpp).

prototype is simplified [O. Galibert]
Beware, the device context does not follow in MCFG_FRAGMENT_ADD
anymore due to the prototype change. So creating a device then
configuring through a fragment doesn't work as-is. The simplest
solution is just to add a MCFG_DEVICE_MODIFY at the start of the
fragment with the correct tag.
