dgen-sdl: Update to 1.33

v1.33 <- v1.32
 * Joystick hat is now handled correctly.
 * Added bindings to switch between previous/next save slots.
 * Fixed joystick calibration issues.
 * Fixed ROM corruption when using Musashi. ROM was not actually read-only.
 * Fixed support for overlapping save RAM and ROM areas.
 * When only Musashi is compiled-in, ROM is not byteswapped anymore to
   improve performance.
 * Disabled automatic ROM checksum fix as it prevents a few ROMs from
   working correctly. Can still be done manually.
 * Debugger: fixed Musashi disassembler to avoid truncating values read
   from memory.
 * Debugger: removed dependency on Musashi. Debugger support can now be
   enabled without it, but it won't be able to disassemble M68K code when
   doing so.
 * Debugger: M68K debugging is now supported by all M68K cores (Musashi,
   StarScream and Cyclone).
 * Debugger: fixed Z80 endianness issue when displaying registers.
 * Improved Z80 BUSREQ/RESET IO read emulation to fix a few games that rely on
   prefetched PC data when reading these addresses.
 * Implemented word (16 bit) memory callbacks for CZ80 to improve performance.
 * Debugger: integrated dZ80, a Z80 disassembler.
 * Fixed interrupt mode 0 in CZ80, fixes sound issues in a few games.
 * Debugger: added full Z80 debugging support. It is supported by all Z80
   cores (MZ80, CZ80 and DrZ80).
 * Fixed CPU dump/restore routines which caused games to crash when switching
   between CPU emulators.
 * Fixed DrZ80 documentation about its Z80 state structure. Modified DGen
   accordingly to solve dump/restore issues.
 * Replaced bool_opengl_aspect with bool_aspect, which also forces scaling
   by the same amount in both directions.
 * Merged scaling and pre/postscale filters APIs. Crap TV filters and scalers
   (scale2x, hqx) now use a similar API. Makes things a lot simpler.
 * Added "stretch" filter to replace the basic scaler. As its name \ 
suggests,
   this filter can stretch the picture to fit the window size and is as fast
   as its predecessor. Useful when OpenGL cannot be used.
 * Since filters can be stacked, added two combinations: scale2x + stretch and
   hqx + stretch. Obviously slower than scale2x or hqx alone, but allows
   picture to fit the entire window while looking nicer than simply
   stretching it.
 * Refactored screen initialization, window size is now completely free and
   never modified by DGen/SDL (except during init).
 * Disabled save/restore when no ROM is loaded.
 * Added config_save and config_load commands.
 * Calibration screen is not a CTV filter anymore and is always available.
 * Added preliminary support for Sega Pico.
 * Added VGM dumping functionality (vgmdump command).
 * Fixed DAC data type for Cyclone (distorted sound due to improper type
   conversion).
 * Improved DAC rendering for much better sound quality (try Tiido's Tempo
   Theme ROM). The default sound rate is now 44100Hz instead of 22050Hz.
 * Added missing YM2612 and DAC information to save states.
 * Fixed pbm2df issues on Windows by open files in text mode.
 * Fixed bind_* commands to run only once.
 * Added support for key/joystick button combinations bindings. In short,
   pressing several buttons simultaneously to execute a command (such as
   quitting DGen/SDL) is now supported. See documentation.
 * Merged stopped and main events loops to remove some redundancy.
 * Added standard bindings for Pico pen.
 * Added mouse input support. Mouse buttons and axes can be bound like any
   other controller (also added mou_* variables similar to joy_* and key_*).
 * Fixed sound (re)initialization which sometimes caused sound to stop after
   loading a ROM.
 * Added various workarounds for fbcon (Linux's framebuffer). A common issue
   is screen blinking due to double buffering, now disabled by default.
   Inability to run as a normal user due to missing mouse input and hanging
   during SDL_SetVideoMode() are also worked around.
 * Usual bunch of miscellaneous bugfixes and improvements (libarchive API
   update, many compilation warnings and other issues introduced by recent
   changes).
