Enable multi-touch emulation with -gpu on
This CL implements a callback that gets invoked by OpenGLES emulator on it framebuffer
updates. This allows transferring framebuffer changes to the supporting device.
Proper implementation of this new callback also required changes to JPEG compression,
addressing:
1. OpenGLES framebuffer format is RGBA8889, which required implementing line conversion
for this format.
2. OpenGLES framebuffer is (or at least could be) bottom-up arranged. This requires changes
to the compressor, so it compresses the FB starting from the bottom, so the resulting
image is up-bottom.

Enable RGB565 input color format
This change enables compression of RGB565 input to YCbCr (default) output format.
Main intention for this change is to enable the emulator to directly compress
RGB565 framebuffer without converting it into RGB888 prior to passing it to the
compression routine.

Include JPEG compression / decompression library into emulator build
We are going to need JPEG compression for transferring emulator's framebuffers to
the multi-touch supporting application running on an android device. The source
for JPEG compressor has been copied over from external/jpeg
To that I've added distrib/jpeg-6b/sources.make containing build instruction for
JPEG compressor. That file gets included into Makefile.common to compile JPEG
compressor sources along with the emulator sources.
