get rid of wrapper function RefreshScreen and replace with PutImage

for 8bit and 32bpp colorg

#90 add option to store changes to single DSKs and DSKs in M3Us (multidisk) in RetroArch SRAM (.srm files) (#111)

* #91: Optionally create empty disk images. Also show a notification when DISK.ROM is required but not loaded

* quick disk swap

#100 overscan

- optionally load MSXDOS2.ROM, to provide Disk BASIC 2.01
- set RA region to NTSC or PAL depending on FPS 60 or 50
- load GM & GM2 in external slot A (in B in a few cases) to enable proper function on all platforms & independent of other optionally loaded ROMs
- describe slot & memory layout for MSX1 & MSX2/2+ models as implemented by fMSX

Fix tearing due to displaying video buffer at scanline 192. Also implement dynamically switching between 50Hz/PAL and 60Hz/NTSC. (#101)

- emulated keyboard; first 6 inputs were incorrectly set as joystick events
- FLUSH_ON_CLOSE for multidisk
- RTC initialisation

- add 7 unmapped keys: DEAD (accents) and numeric pad. Note: Numpad period key presses seem unregistered in RA (on Linux)?
- #44 mention in readme that Turbo-R is out of scope; not part of fMSX

- remove AY8910_DRUMS, MSX_DRUMS & various other obsolete MIDI #defines
- document limitations of fMSX sound emulation & channel usage
- remove PChanged (patch, i.e., instrument) & DChanged (drum) attributes of OPLL; both were only used for MIDI logging (fMSX/X) or actual MIDI playback (fMSX/Win) - which hardly sounds like the real thing
- remove 3 obsolete tables for OPLL (YM2413)

- retro_unload_game(): invoke TrashMSX()
  .. and solve free() problem related to getcwd()/WorkDir
- explicitly #define NUM_FDI_DRIVES 4 (differs from MAXDRIVES, which is 2 for MSX!)
- rework PATCH_Z80 Makefile cfg
- fix 192kB VRAM using proper bitmask

* Support fMSX .CHT and blueMSX .MCF cheat files

MCF support was already rudimentary present in fMSX.

* refactor logging & messaging after merge

* remove dead code & unused features: effects, image-related code, dummy HID methods Keyboard() & GetJoystick(), debug console-related code, I8251.c/h serial COM, printer, EMULib.c, LoadFile()

* update readme

- fix maximum VRAM size - 192KiB (12 pages) was selectable in libretro.c but capped at 128KiB in MSX.c (#82)

- support maximum RAM size (256 pages of 16KiB = 4MiB)

More detailed:
- autodetect .cas format and start it
- link F6 to 'rewind tape' - equal to fMSX keymap
- remove 3 obsolete source files (ConDebug.c, Debug.c, State.h)
- remove 2 unused method headers (InitMachine & TrashMachine)
- resurrect Patch.c; required for Cassette and fmsx_simbdos
- remove Guess Mapper Type B; fmsx-libretro supports only 1 ROM (thus A)
- also support .FDI disk format
- fix inline redefinition warning
- refactor VFS forward declarations

Add option fmsx_font, to load a fixed text font

Add option fmsx_allsprites, which shows all sprites

fix & document keyboard map

Add option fmsx_allsprites, which shows all sprites, i.e., lifts a video chip hardware limitation, which is reproduced faithfully by default. Makes for just a tad nicer (though less nostalgic) playing experience in games like Zanac.

- map COUNTRY & STOP equal to fMSX
- document RetroArch-to-fmsx control mapping, including MSX2+ Japanese
