Added minimal support to command buffer for GL_ARB_texture_rectangle

textures, and added Mac OS X-specific extension for binding IOSurfaces
to textures. This is infrastructure work for rendering Core Animation
plugins via Chrome's compositor.

Refactored the texture initialization in the command buffer and
associated unit tests. Added unit tests for rectangular textures.

These changes will be hooked up in a subsequent CL. They were split
off for easier review.

There are ongoing discussions about unifying the various mechanisms
for sharing textures across processes, but it's been agreed that those
should not block this work.
