* Added ps2timer device to encapsulate Playstation 2 timers.
* Temporarily hacked R5900 core to always have scratchpad RAM mapped at 0x70000000.
* Added reference counting to divtlb so that it does not unmap pages that are still shared with other entries.
* Added a considerable amount of logging to ps2sony.cpp.
-mips3: Added basic Emotion Engine support. [Ryan Holtz]
* Added S bit to TLB mapping.
* Added support for VSUB, VIADD, VSQI, VISWR, VOR, LQ, SQ, MFSA, MTSA, MFHI1, MFLO1, MULT1, DIV1, DIVU1, PEXTLW, PADDUW, PMFHI,
PMFLO, PCPYLD, PCPYUD, SQC2, LQC2 opcodes. [Ryan Holtz]
* hp9k_3xx: fix timer connection for /320 models

* hp9k_3xx: add HP9122C floppy
Remove HP9895 from the default configuration. 3.5" where
standard on /300 and there's almost no software on it available.
If a user really needs 8" floppy drives on /300, he can do that via
commandline.

* add Intel i8291a GPIB Talker/Listener
Required for the HP 9122C floppy, and used in many other devices.
Basic functionality was implemented to make the HP 9122C work, a few
things are still missing and will be added later. Most of the missing
things where simply not used in the HP9122C so i cannot test them.

* Add HP 9122C floppy drive
These drives where common on HP9000/300 workstations. With the current
implementation TD0's from hpmuseum can be used to boot, and initializing,
reading and writing discs in HP basic works. Tested both high and double
density media. Supported Media formats are TD0 and MFI.

Poly 1 Educational Computer (early) [Nigel Barnes, Andrew Trotman]
Poly 2 Learning System [Nigel Barnes, Andrew Trotman]
Poly Development System [Nigel Barnes, Andrew Trotman]
Merged with strnskil.cpp, with modernization and cleanups. (nw)
Add MCFG_SCREEN_RAW_PARAMS. (nw)
Added coin counters to markham, strnskil, banbam and clones.
* softfloat3: do we like this better? (nw)
* softfloat3: it gets the hose again (nw)
* softfloat3: sonofa (nw)
* interpro: wip checkpoint (nw)
* added 6x00 models
* added EDGE graphics skeleton
* split bus/cards into two types
* various fixes/changes
* proposal: move z80daisy* to devices/machine
Seems to me this is a machine, not a CPU? Main reason was to stop the Z80 CPU from being dragged into systems that don't have one just because they use a Z80 family peripheral.
* missed this one (nw)
* missed a spot (nw)
* softfloat3: fix msvc build (nw)
Is this how we do these things? I assume we don't touch the library code itself, and have to "fix" any problems via this header instead?
* softfloat3: do we like this better? (nw)
* softfloat3: it gets the hose again (nw)
* softfloat3: sonofa (nw)
This is a pre-usage import so everyone can get things in line for various compilers. GCC/Clang should be OK on most targets as-is;
MSVC may need to edit 3rdparty/softfloat3/build/MAME/build.h to conform. Please report failure/success with various compilers.

* interpro: slotify mouse (nw)
Needed to make the mouse a slot device to enable it to be connected to graphics boards under development.
* add validity check (nw)
* bt45x: new devices
Basic implementation of various Brooktree RAMDAC devices. Two of these (bt457, bt458) are used by InterPro graphics boards currently under development, the others are unused/untested at this point.
* bt45x: tweak descriptions (nw)
