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.

Split grayscale library into several files to make up a real function library. Significantly decreases binary size for plugins using it.

Major rework of the grayscale framework:
...
* api change - all drawing functions now use draw mode, foreground and
background shades set globally by separate functions
* There are now 4 draw modes for all drawing functions, no more separate
functions for inverse drawing
* Significant speedup of 1-bit bitmap (and font) drawing (2..3 times)
* Some more speed tweaks
* Additional functions for horizontal and vertical lines
* Copied describing comments to the header file for easier reference
* The safety net against an uninitialized grayscale buffer is gone
