[Mesa-dev] [PATCH 11/38] main: Major refactor of get_texture_for_framebuffer.

This splits off the (still) rather large chunk that is
get_texture_for_framebuffer into lots of smaller functions specialized to
service the wide variety of unique needs of *FramebufferTexture* entry points.
The result is much cleaner because, rather than having a pile of branches and
confusing conditions (like the boolean layered), the uniqueness is baked into
the entry points. The entry points know whether or not they are layered or use
a textarget.
