Improvements to almost all games in skylncr.cpp

- Use standard input mappings in all games except Sonik Fighter
- Add working hopper outputs and payout buttons
- Promote mbutrfly to WORKING after solving the protection (the code wasn't encrypted) and add the button lamps internally associated with it
- Decrypt bdream97, which is almost working now with obvious graphical glitches and some apparent input problems
Slight error logging elaboration for illegal Z80 instructions (nw)

This should hopefully prevent the sub CPU from locking up (and making
controls unresponsive) in technodr.

Make Techno Drive working, fix H8 ADC inputs.

This was broken in a rewrite a long time ago, breaking the controls in
some Namco System 12 (and probably 23) games.
This commit improves controls in golgo13, g13knd and technodr.

Use MAME's type attoseconds_t and handle the timing accus in
attoseconds instead of nanoseconds.
Try to solve the video timing issues by using an emu_timer running
at the field rate of 60Hz, which the video state machine synchronizes to.

Refactor the display to use a buffer of the size of the total margins.
Remove the deprecated MCFG_SCREEN_REFRESH_RATE().
Try to synchronize the CPU on the vertical sync generated by mame
calling the screen_update() function.
Instead of a fixed CROM/CRAM configuration defined through macros,
make this a machine configuration parameter. You can now choose
between the 3 setups:
1 = 1K CROM, 1K CRAM, 1 S register bank
2 = 2K CROM, 1K CRAM, 1 S register bank
3 = 1K CROM, 3K CRAM, 8 S register banks
TODO: Some games which used to work in Salto do no longer work with
this driver, e.g. pacman7 from the allgames.chd

There was little to no advantage in calling the various subdevice
bs, f1 and f2 early/late functions through function pointers.
The original idea was to make this configurable, which it isn't.
The hardware, or schematics, define the functions and they are
(almost entirely) static anyway.
By removing the function pointers and inlining the appropriate calls
into switch/case statements there's a speed improvement of ~ 2.5x here,
seen while the diablo bitclk is not running.

declarations in code, and a first pass at the required core changes
to unpack tiny_rom_entry structures at runtime.
WARNING - I've done preliminary testing on a tiny build (pacman works), but nothing more. I know for a fact that a full compile fails

Instead of using a number of UINT8 with the decoded bit fields of the
MIR (micro instruction register), add inline functions to extract the
bits from m_mir. That ought to be faster, because there are fewer memory
accesses in cases where bit fields are not actually used by an instruction.

The frame rate is really 30 frames (60 fields) per second.
Reading memory after cycle #5 after the MAR<- is possible, because
the Alto 2 contains a latch for the most recent RAM dword.
Thanks to the LCM and ContrAlto source for the hint!

Save copying odd / even frame scanlines by immediately updating
the m_dsp.bitmap when a frame buffer word changes.

Removed dead and unused code while searching for the bug which
causes the jiggly mouse cursor display. No success yet.

- Remove irq_line methods from M6502, M6800, M6809, S2600 and replace uses with DEVCB_INPUTLINE
- Remove a few IRQ passthroughs from spiders.cpp
- Add several aliases for M6800_IRQ_LINE
