469866b6c9 mpegplayer: Fix aliasing rules violation on multi-core targets 
As the PP series has no sense of cache coherency between its multiple
cores, we need to ensure the vo_data structure does not share cachelines
with anything else.

This was previously done by defining a uint8_t array and trying to
access it via typecasting hell, triggering a large pile of aliasing
violation warnings on newer toolchains and/or higher optimization
levels.

Instead of violating the C spec in an undefined-behaviour-sort-of-way,
create a union of the right size and alignment, and make one of its members
the structure we care about.  Voila, everyone is happy.

31af1a3ac2 MPEGPlayer: Move some code that's probably better situated in the stream manager rather than the parser. Fix visibility checking in video out. Extra message sending for new stream isn't needed; just do full decoder sequence reset when requesting dimensions.

bc26fe7a96 Add a wrapper header, mylcd.h, in the lib subdirectory, which lets plugins' code automatically call the proper functions depending if compilation is for greylib or color display, also forms proper call to grey_ and xlcd_. mylcd_ub_ call greylib unbuffered routines, regular lcd routines otherwise. Form is mylcd_<fnname>, <fnname> is the symbol name stripped of prefixes lcd_, grey_, or xlcd_. Convert a couple plugins I know well (easy job).

05099149f1 Enable nocache sections using the linker. PP5022/4 must use SW_CORELOCK now with shared variables in DRAM (it seems swp(b) is at least partially broken on all PP or I'm doing something very wrong here :\). For core-shared data use SHAREDBSS/DATA_ATTR. NOCACHEBSS/DATA_ATTR is available whether or not single core is forced for static peripheral-DMA buffer allocation without use of the UNCACHED_ADDR macro in code and is likely useful on a non-PP target with a data cache (although not actually enabled in config.h and the .lds's in this commit).

68a21689ae Consistent naming scheme the various blit functions. * Removed lcd_blit_mono() for colour targets. Plugin API became incompatible, so sort, clean up & bump. * Implemented lcd_blit_mono() for M3.

feb5b15e9b All-new greyscale library, replacing the old one. Features: (1) Drawing/updating is faster than the old grayscale lib at full depth. (2) Always 129 shades instead of 2..33 shades. (3) No graininess caused by frequent updates (mpegplayer, doom, ...). (4) Needs less memory than the old grayscale lib at full depth. * The tradeoff is slightly higher CPU load in the ISR (frames are calculated 'live') and an extra function in the core. * Ported all plugins which used the graylib to use the new one. * Some slight optimisations for archos and H1x0 LCD update.

a5fc3f4df4 Initial WVS for mpegplayer. Adjusts to the user's preferred font and uses FF/RW preferences set for playback. Picked a random color for the base WVS color but it could be configured. Some engine tweaks to accomodate it since certain nescessities are clearer now. Fix a clipped YUV output bug in the SIM.

a222f27c4a mpegplayer: Make playback engine fully seekable and frame-accurate and split into logical parts. Be sure to have all current features work. Actual UI for seeking will be added soon. Recommended GOP size is about 15-30 frames depending on target or seeking can be slow with really long GOPs (nature of MPEG video). More refined encoding recommendations for a particular player should be posted soon.

c8e69dfb71 Move FPS display out of video_out_rockbox.c and into mpegplayer.c. Also add frame-rate limiting and frame-skipping (skipping display only, not decoding) to try and achieve real-time playback. Frame-rate limiting and frame skipping (and FPS display) are enabled via options in a new menu and are currently all off by default.

c9d66562af Initial commit of work-in-progress MPEG video player plugin based on libmpeg2. Works on all targets with colour LCDs, but most optimised for the ipod Color/Photo and Nano. It currently only plays raw MPEG-1 or MPEG-2 video streams (no audio). Also adds a new lcd_yuv_blit() function to the plugin API - currently only implemented for the ipod Color/Photo and Nano.
