Android: Rewrite lcd subsystem to use the SurfaceView API.

That enables drawing from outside the apps UI thread, i.e. from within the Rockbox native thread, without needing synchronization means, and adds determinism as to when the draw happens.
It simplifies the drawing routines and adds a convinient way of detecting whether drawing should happen or not (surfaceCreated/Destroyed).
It also restores max. fps on my phone which went down drastically with the gingerbread(CM7) update.
