glx: Import glxvnd server module (v2)

This is based on an out-of-tree module written by Kyle:

https://github.com/kbrenneman/libglvnd/tree/server-libglx

I (ajax) did a bunch of cosmetic fixes, ported it off xfree86 API,
added request length checks, and fixed a minor bug or two.

v2: Use separate functions to set/get a context tag's private data, and
call the backend's MakeCurrent when a client disconnects to unbind the
context. (Kyle Brenneman)
