mesa: Add new MESA_multithread_makecurrent extension.

This extension allows a client to bind one context in multiple threads
simultaneously.  It is then up to the client to manage synchronization of
access to the GL, just as normal multithreaded GL from multiple contexts
requires synchronization management to shared objects.
