Grayscale library ported to the grayscale iPods, first version. Added C reference versions of gray_update_rect() for both horizontal and vertical pixel packing. gray_update_rect() and gray_ub_gray_bitmap_part() not yet assembler optimised. Grayscale screendump doesn't work yet. * Fixed button assignments for iPod in grayscale.c

Finally - grayscale library support for the simulators. Currently SDL only, win32 and x11 won't link anymore due to missing simulator functions.

Changed the LCD_COLOR pixel value format to packed RGB (unsigned int). Now all LCDs with depth > 1 use the same datatype. Added macros for easy pixel value definition.

Grayscale library: (1) Ported to iriver H1x0. Experiments have shown that the intended 49-shade mode isn't possible due to interference between the internal greylevel generation of the LCD and external pixel flipping, so the lib allows 33 shades as on the Archos. The current implementation wastes RAM by not switching the LCD to b&w mode and simply using colours 0 and 3 only. However, this allows to show a partial greyscale overlay and normal 4-shade graphics in parallel. (2) Converted all asm blocks to use symbolic parameters. (3) Properly marked asm input parameters that are changed within the block as in-out and feed them from a temp variable where necessary. (4) Screenshot is not yet working on H1x0.

Complete rework of the grayscale library: (1) Implemented the new rockbox graphics api. (2) Added buffered mode, and implemented most drawing functions for buffered mode only. Buffered mode will ease implementation of animated graphics. Some functions are additionally provided as unbuffered versions (drawing grayscale bitmaps, scrolling) since unbuffered mode is better suited for non-animated graphics (JPEG viewer, mandelbrot) and saves some RAM, which is important on Archos. (3) Put all functions in a couple of source files, no more one-function-per-files. This became possible since sectioned compilation for the plugin library and appropriate linking for the pluginswas introduced, otherwise the binaries would be bloated by unused functions.
