There are two parts to the change. First is a correction to the coco_fdc
hardware emulation. Second is file format ordering adjustments wich make
things easier for using FLEX on CoCos.
For the hardware change: Before the change FLEX was unable to boot on CoCo
machines. The behaviour and troubleshooting showed that while the FLEX
kernel started up it was unable to read anything from Track 0. Standard
FLEX disks have SD(FM) on Track 0, and the remainder of the disks (for CoCo
FLEX) are normally DD(MFM) or could also be SD(FM). The bug was in the
handling of the WDC FDC's INTRQ line. Reviewing the available
documentation and schematics showed that when the FDC asserts INTRQ two
things happen. NMI is asserted on the CoCo bus and the HALT signal is
cleared. The MAME code added an incorrect condition on clearing HALT: It
only happened when Double-Density operation was selected. This change
fixes the logic to work the same way as is shown in the schematics, that
HALT is cleared any time INTRQ is asserted. SD(FM) disk operations work
properly and FLEX boots completely and runs correctly after making this
change.
File Format Ordering Adjustments: This part of the change makes it easiser
to use FLEX in CoCo emulation with a wider variety of FLEX-formatted disk
images. The issue here is that due to the way the JVC disk format works it
winds up being a catch-all for disk images. Because FLEX has specific
formatting requirements and code to handle this and JVC has no support for
this special formatting, FLEX formats along with DMK and SDF are moved to
come before JVC in the formats list. This allows a wider variery of
FLEX-formatted disk images to be properly detected.
The DMK disk image from the following recent restoration of FHL Color FLEX
was used for testing:

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.

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

* Allows defaulted clocks (see subtle example with vboy)
* Allows additional constructors (see RS232 port in tranz330)
* Allows use of device finder in place of tag in MCFG_DEVICE_ADD
* Requires out-of-line destructor for devices using incomplete types
* Requires XTAL or explicit u32 for clocks for devices with private types
Devices must still define the standard constructor. When writing
additional constructors, be aware that the constructor runs before
device_add_mconfig in the context of the existing device, not the new
device. See osborne1, zorba, tranz330, and vboy for examples of this in
use. Compilation is a bit slower, but this is temporary while
refactoring is in progress.
Eliminated the need for MCFG_SOUND_ROUTE_EX.
Removed macros from slot option configuration - they just obfuscated
code and slowed it down with needless dynamic casts, but didn't actually
simplify it.

Concrete device types now have a call operator that instantiates a
device.
This change means you *must* use DECLARE_DEVICE_TYPE to declare the
public interface of your device, even if it's device_t. If you want
to use private implementation classes, use DEFINE_DEVICE_TYPE_PRIVATE
and instantiate the object finders.

* Added COCO2_DW1 to cart devices for the Color Computer 2/2B that has the CoCo 1/2 series of systems.
Added unofficial systems CoCo2DW1 and CoCo2BDW1 for use with the CoCo 2 series of DriveWire Becker Port.
* Added coco2dw1 and coco2bdw1 to mame.lst file.
* Removed coco2dw1 and coco2bdw1 as requested.
COCO2_HDB1 is cart slot device and is still intact.
* Removed the coco2dw1 and coco2bdw1 from the mame.lst file.
* Had to add cc2hdb1/COCO2_HDB1 to coco_multi.cpp so the COCO2_HDB1 cart would be usable in the multipak device.

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.

Thanks to Daniel Campos & Datassette.org for the CP-450 disk rom. MAME was calling it CP400_FDC, but the correct name of the disk controller unit is "Prológica CP-450". The ROM was correct (verified checksum), but I renamed it to fix the previous naming mistake. Unfortunately this FDC unit is rare, so I still don't know whats the IC reference for the EPROM on the PCB.
There is a photo of the CP-450 disk controller unit at:

* [CoCo] Follow up hygiene on CoCo cartridge slot refactoring
- Removed now-extraneous cart_set_line() specific to the FDC code
- Added typedefs for line and line_value within device_cococart_interface()
- Moved private TIMER_* declarations to source file
- Added overload of set_line_value() that takes a 'bool' instead of 'line_value'

(nw) This is a pretty minimal change. The point where the root device is added has been moved
from the MACHINE_CONFIG_START macro to the constructor of the machine configuration class (made
possible by giving drivers their own device types). This isn't the final change in this area.
The root device is still being handled specially in that its configuration comes from the game
driver structure. This needs to be harmonised with regular devices. But that's a job for
another day.

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.
