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.
