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.

-* This is a generic framework to use grayscale display within Rockbox
