* Made a cleaner, thread-safe API for getting volume names.
* Added compile-time option to disable recompiler W^X mode.
* NuBus image device current directory doesn't need to be pinned.
- render.h: Split out layout class declarations into rendlay.h, with some adjustments for the resulting incomplete types (std::reference_wrapper unfortunately does not allow these by C++17 rules)
- rendlay.h: Move old header contents to layout/generic.h
- vecstream.h: Revert changes made in aa29519528. The std::string_view conversion has been made a non-member function (util::buf_to_string_view) and moved to coretmpl.h.
- strformat.h: Remove the using declaration importing util::string_format into the global namespace. It has been moved to emucore.h and a few tool sources; other references have been qualified.
- osdcore.h: Split out file, directory and path classes and methods to a new header (osdfile.h), Doxygenizing the documentation comments.
- Disaggregate many #includes that were including other standard or custom headers. emu.h now includes basically the same things that it did, but other headers have been streamlined; for instance, emucore.h no longer stealth-includes osdcore.h several ways.
* shuffle a few things around re: the BBL ST2302U based handhelds, give bbl338 its own map due to internal ROM etc.
* fake some interrupts on bbl338
* better document test draw command, so that we can verify we're in test mode

-st62xx: Various changes. [Ryan Holtz]
* Fixed RETI and LD rr,A opcodes.
* Optimized internal register handling.
* Converted to use logmacro.
* Added initial timer support.
* Started moving Lua class reference to docs. Expecting people to find
the class reference material in the source isn’t going to help make it
approachable. The docs allow longer explanations, better formatting,
and cross reference links.
* Added another layout scripting example to the docs.
-goldnpkr.cpp: Minor clean-up.
* Improved the short names for Witch Card and Witch Game clone sets.
* Made Witch Up & Down artwork clickable.

a readon.
* set additions, see main decription
* not working additions, see main description
* more not working bits, see main description
* more not working additions, see main description
* consistency fix
Added methods for enabling and disabling breakpoints and watchpoints,
and made debugger views update when breakpoints/watchpoints are
manipulated from Lua. Made breakpoints and watchpoints objects rather
than tables. (It’s not possible to enable/disable a breakpoint or
watchpoint from the object itself, you have to go through its owners'
debug interface.)
Exposed more device_t members for dealing with child/sibling tags and
devices. Also provided a way to get regions/shares/banks from a device
using relative tags rather than going through the memory manager with
absolute tags.

* Need a safeguard somehow, and a symbols build doesn't help here lalala
* Fix notes, cannot repro the bug, next
* Move irq assert/clear lines to device, add preliminary prg timer, make 30 Hz irq to behave like one.
(Note: very untested, feedback is appreciated)
* Send a prg timer ack if irq is disabled
* Misc cleanups
* Nuke emu_timers in favour of configure_scanline, preliminary bnstars1 hookup
* No magic number please
* Add sysctrl to tetrisp2.cpp, move rockms stuff into its own state machine, misc
* Kill off 30 Hz refresh rate hack in stepstag/vjdash sub screens
* Flag all those xtals as unknown
* Move has_zoom/has_yuv in ms32_sprite init constructor, fix dummy config bug with stepstag right screen update
* jalcrpt.h doesn't belong to tetrisp2.cpp, errata on sysctrl reset line

* Fix crashing in main ms32 driver, except it now has very broken priority for seemingly no reason
* Fix nasty spriteram buffer RAM allocation bug
* Make objectram_size to be calculated at init time

* Move f1superb to own state
* MS32 merge sound maps
* Remove TIMER_DEVICE_CALLBACK_MEMBER in favour of emu_timer
The things that were previously called device iterators are not
iterators in the C++ sense of the word. This is confusing for
newcomers. These have been renamed to be device enumerators.
Several Lua methods and properties that previously returned tables now
return lightweight wrappers for the underlying objects. This means
creating them is a lot faster, but you can't modify them, and the
performance characteristics of different operations varies.
The render manager's target list uses 1-based indexing to be more like
idiomatic Lua.
It's now possible to create a device enumerator on any device, and then
get subdevices (or sibling devices) using a relative tag.
Much more render/layout functionality has been exposed to Lua. Layout
scripts now have access to the layout file and can directly set the
state of an item with no bindings, or register callbacks to obtain
state. Some things that were previously methods are now read-only
properties.
Layout files are no longer required to supply a "name". This was
problematic because the same layout file could be loaded for multiple
instances of the same device, and each instance of the layout file
should use the correct inputs (and in the future outputs) for the device
instance it's associated with.
This should also fix video output with MSVC builds by avoiding delegates
that return things that don't fit in a register.

The project won't move forward if we're not proactive about ensuring
legacy code isn't added. In particular, this PR contained the kind of
code that we need to remove in order to be able to move to proper
per-device outputs and to allow clients to enumerate a system's outputs
on start; and runtime tagmap lookups for I/O ports, which can't be
checked on validation and hence require exercising all code paths to
detect errors (as well as the performance issues).
The pull request had outstanding reviews requesting changes. It's not
acceptable to ignore that and merge it.

This fixes the "typing on all keyboards at once" issue. You can now
enable and disable keyboard/keypad inputs per device in the Keyboard
Mode menu. Default is to enable the first device with keyboard inputs,
and all device with keypad inputs but no keyboard inputs. The settings
are saved in the CFG file for the machine.
Typing in natural keyboard mode only ever types on one keyboard at a
time, but now you can control which keyboard it types on, as it will be
the first enabled keyboard.
You can easily try this out with something like:
mame64d zorba -rs232 terminal cpm
-ui/inputmap.cpp: Show device descriptions as well as tag paths.
-mac128.cpp: Fixed mouse axis wrap compensation, cleaned up mouse code,
eliminated static variables for mouse input state.
You could see the issue with wrap detection easily enough just by
running mac128k/mac512k/macplus and tapping the arrow keys to move the
mouse one pixel at a time. As you moved past the point where the axis
count wrapped, it would move one pixel in the opposite direction.
There were two function static variables related to mouse input state,
probably still lurking from when the code was initially made to use a
driver state class. This obviously messes with save states and prevents
multiple instances.
- bus/a2bus/mouse.cpp: Fixed mouse axis wrap compensation.
This device had the same bug with wrap compensation as mac128k.cpp.

vsmile_cart: V.Smile Tanz Mit Center (Germany), V.Smile Défi Gym (France), Gimnasio Interactivo V.Smile (Spain)
-vsmile: Added support for the Jammin' Gym Class dance mat. [bmx, Ryan Holtz]
* Split hc55516 core into separate cores/subclasses for hc55516 and hc55532 (new 'digital' implementation based on decap/die tracing) as well as mc3417 and mc3418 (old existing 'analog' implementation left alone) and hooked the hc55516 and mc3417 implementations to the appropriate hardware drivers. This should vastly improve CVSD sound quality in drivers that use the hc55516. [Lord Nightmare, Sean Riddle]
* Made Exidy's mouse trap use a timer to clock the mc3417 and update the state readable by the z80 rather than relying on the mc3417 to accept a clock parameter and update the z80 state via a callback. The timer implementation ensures proper synchronization and prevents missed clock transitions from the z80 side causing noise in the CVSD audio. [Lord Nightmare]
* Added a biquad-based 2nd order filter emulation for an audio stream (to go along with flt_rc 1st order filter emulation) and hooked it to Exidy's mouse trap (mc3417) and williams drivers (hc55516) following the original schematics. For hc55516 this is necessary as the original chip produces a very pronounced audible 16khz 'carrier' in its output audio even on the real chip, and these filters suppress this. This also happens to a lesser extent with the 8khz quieting waveform noise on both mc3417 and hc55516. [Lord Nightmare]
* Made Williams System 11 and s11_bg relative sound mixing more accurate to the original audio flow on the PCB itself. [Lord Nightmare]
* Switched Williams Joust 2 to use the s11_bg common sound device rather than its own implementation. [Lord Nightmare]
Also improved symmetry of disk components, fixed positioning of
components when fitting to the pixel grid, and fixed inherited color
when item has no color specified.
Removed the dotmatrix components from complay.py - there are more
flexible ways to achieve the same thing.
* fmtowns: add a SCSI card slot for the original models
- Add a slot device for the Model 1/2 dedicated SCSI slot
- Add a device for the FMT-121 SCSI Card
- Modify the I/O maps and machine configurations so the slot and the
integrated controller don't overlap
Moved MS DIB parser out of ICO file reader and made it available for
artwork and layout images.
Added more efficient I/O and better error checking for JPEG file loading
(MAME will no longer exit immediately on a bad JPEG file).
Made caller responsible for opening files for loading images, to avoid
decompressing images used in ZIP/7z artwork multiple times.
Added support for JPEG and Windows DIB to picture_image_device.
Added support for SVG image files in external artwork.
Added support for using I/O port value for animation state and masking
animation state values.
Made bounds elements more flexible in layouts.
Reworked headers to reduce dependencies.
Updated layout file format documentation.

TV MegaMax active power game system 30-in-1 (MegaMax GPD001SDG) [David Haywood]
* added files for the VT APU type, currently no extra functionality, but will be built upon
* psixptty: Fix for FreeBSD
We need to check for __FreeBSD__ not __FreeBSD_kernel__
* FreeBSD: Use gl includes from pkg-config
FreeBSD doesn't install the includes from 3rdparty software in a default
location so use pkg-config to get the correct path.
* FreeBSD: genieos is named simple bsd
- Hook up periodic and keyboard interrupts
- Implement keyboard and hook it up
- Render according to vram address and add basic cursor support
- Hook up bell sound
* Most OpenGL link issues fixed. Two remain from drawogl.cpp.
This isn't working anyhow.
* "-video accel" now uses WebGL. This allows GL based scaling and
provides a performance improvement.
* Fixed pong and other games by adding another function to the
exception whitelist
* Target now is mame.html. This allows emrun to be used for testing.
mame.js is created as well and thus the current behaviour
unchanged.
This adds support for the mini digital cassette recorder that can be
found inside a P2000t. This implementation is based on documentation
that can be found in https://github.com/p2000t/documentation.
In memory of NPM Jansen, who taught me all the magic of bits and bytes.
Components may have multiple bounds and/or color child elements with
state attributes, allowing for piecewise linear position/size/colour
animation.
Components may have a statemask attribute, allowing for things like
using external images to draw a multi-segment LED/VFD display without
requiring dozens of outputs for the individual lines or thousands of
images for all possible states. (Texture caching still never releases
anything, so MAME can still exceed the maximum number of textures, but
that’s a separate issue.)
Image components with alpha now blend over previously drawn components.
Layouts have been changed to use yes/no for inputraw to match what's
used for flipx/flipy. External layouts with 1/0 will still work, but
complay.py will complain.
* animalc: Pile kludge upon kludge for poorly understood video timing register
* gocowboy, itazuram: Increase frequency of one timer interrupt (and hopper timing in gocowboy)
* kc82, kp69: Modernize state_add syntax
* Removed device and macro header files.
* All of those can be generated automatically so going forward there is
no need for these any longer.
* Introduced the modules concept. Modules are netlists for which
automatic lib entries are generated.
* Going forward you just store them in macro/modules and they will be
automatically registered as device elements.
* You need to do a "make generated" is src/lib/netlist/build
* Some_device.cpp still needs to be added to netlist.lua
* Added documentation on how to add devices to netlist.
* Please refer to adding_devices.md for more information.
These layouts have changes to element stacking order that can't be
avoided without changing the group structure in the layout files. I
think it's harmless, but it's possible it could have had a detrimental
effect on risc2500 (I tested it and didn't see any changes, but I might
not have known what to look for).
-complay.py: Added basic checks for dupicate collection names.
As with other checks of this kind, it doesn't actually instantiate the
layout so it doesn't check things when variable substitution is
involved.
Changed name of element to "collection" and initial visibility attribute
to "visible", and added them to documentation. Also added them to
complay.py.
Fixed issue with collection inside group, and improved initial view
selection behaviour.
Updated some internal layouts to demonstrate new features, including
et3400, irrmaze, ltcasino, mekd3/mekd4, seawolf and vgmplay.
Removed all uses of cpanel, marquee and overlay from internal layouts
and removed them from complay.py to actively discourage use. Also
cleaned up view names in layouts that were using them in place of
spaces, and removed some superfluous name attributes on elements that
won't do anything useful with an output value anyway.
Made vgmplay cycle visualiser modes when visualiser screen is clicked.
Fixed a copy/paste error in bus/rs232/hlemouse.cpp while I'm at it.

* Implemented wait states and the vector DRAW flag to help improve timing.
SP0250 Improvements: [Aaron Giles]
* Matched clock divider to real chip measurements.
* Fixed behavior when not fed enough data; addresses "gapping" in speech in Sega games.
* Implemented accurate LFR noise generator according to real chip measurements.
* Added pulse-width modulation DAC output mode for future consumption by netlist.

8253 PIT changes: [Aaron Giles]
* Added explicit synchronization to all writes.
* Cleaned up some timing calculations to avoid double<->attotime conversions.
* sspeedr: new netlist audio implementation
Netlist-based audio implementation for sspeedr (Super Speed Race, 1979)
derived from Midway audio schematics, and based on that used for
280zzzap (280-ZZZAP) and lagunar (Laguna Racer) in the mw8080bw driver.
The Super Speed Race audio circuits are clearly derived from those games;
the biggest difference is the use of a linear feedback shift register
for noise generation.
* Updated netlist static solvers with recent netlist changes.
IMGUI_DISABLE_OBSOLETE_FUNCTIONS was defined in osd/modules.lua but not
