Subject: remove pixelflinger from recovery

Recovery now draws directly to the framebuffer by rolling its own
graphics code, rather than depending on libpixelflinger.

The recovery UI is modified slightly to eliminate operations that are
slow with the software implementation: when the text display / menu is
turned on, it now appears on a black background instead of a dimmed
version of the recovery icon.

There's probably substantial room for optimization of the graphics
operations.
