--------------------
RS-232 DCE-DCE Bridge
(nw) This is a simple machine for wiring together two things that want
to plug into an RS-232 port. This means that for DCE-like things (e.g.
serial printers) there's no need to create an extra machine to allow
them to talk to the outside world with the null_modem device. (Also
added some asserts, removed a FIXME, and put the swtpc8212 terminal in
the default RS-232 devices.)

Eeekk! [Craig Anstett, Andrew Welburn]
(This new parent set runs on Epos's original Tristar 8000 hardware; the previously dumped set has been tagged as the Pac-Man conversion it is.)
Added ability to compile using float instead of double. Specifically the
the solver as well as the infrastructure now can have their own floating
point type. Currently this is only an academic exercise since
numerically demanding circuits like kidniki only work with double/double
support. Using float here is pushing numerical stability over the
limits.
The long term design goal is too have the matrix type (double/float)
being a parameter.
- solver: align matrix population along the various solvers
- solver: delete dead code
- renamed nl_double to nl_fptype and use nl_fptype where previously
double has been used.
- renamed param_double_t to param_fp_t
* Changed emu_fatalerror to use util::string_format semantics
* Fixed some incorrectly marked up stuff in build scripts
* Make internal layout compression type a scoped enum (only zlib is supported still, but at least the values aren't magic numbers now)
* Fixed memory leaks in Xbox USB
* There can only be one "perfect quantum" device - enforce that only the root machine can set it, as allowing subdevices to will cause weird issues with slot cards overiding it
* Allow multiple devices to set maximum quantum and use the most restrictive one (it's maximum quantum, it would be minimum interleave)
* Got rid of device_slot_card_interface as it wasn't providing value
* Added a helper template to reduce certain kinds of boilerplate in slots/buses
* Cleaned up some particularly bad slot code (plenty more of that to do), and made some slots more idiomatic
* Fixed LOG_WAV_ENABLED_ONLY (m_enable has to be checked only if LOG_WAV_ENABLED_ONLY is set)
Added log data to the right channel of the wave, accordingly to the definition declared in LOG_WAV_VALUE_R
* Fixed an error with tag() returning a ':' and generating a filename not valid in Windows environment
* Added Model Racing "Cane"
* Added Model Racing "Orbite"
* Replaced the char array with a std::string in sn76477_device::open_wav_file to override possible buffer overrun.
Minor cosmetic change in a boolean expression in sn76477_device::sound_stream_update
* Refactored "Cane" related code creating an audio device to encapsulate the audio system
Refactored "Cane" and "Orbite" creating their own classes
Other minor changes in indentation of the source code
* i8251.cpp: required initial state to enable receiver of a 8251a and also to avoid sending start bit to diserial on reset and get framing error
* eispc_kb.cpp: removed need for scheduler abuse as problem is fixed by correcting the init of the i8251 USART on host side instead
* eispc.cpp: removed an obsolete TODO
* eispc_kb.h: removed imperfect_features marking
* epc: Added keyboard LEDs, Caps and Num lock works with current keyboard rom, scroll lock led needs a dump from a newer keyboard
This patch gets it running, and splits it into two front ends, one
being a rs232 bus slot so that is can be used as a terminal option. It
adds the MCM66750 character generator, and implements the MC6845 row
update function. Most of the I/O has been worked out with help from
the CT-82 user manual. The various screen formats and the graphics
modes appear to be working and plausible. Printer support has been
added, and a beeper.
