When GlxGetXIDMap looks up an unknown XID, it will now look up a vendor based
on the screen number for the XID and the client that sent the current request.
In GlxGetXIDMap, if the XID is for a regular X window, then it won't be in the
(XID -> vendor) mapping, so we have to look up a vendor by screen number.
With this change, GlxGetXIDMap will use the (screen -> vendor) map for
whichever client sent the current request, instead of using the global
(screen -> vendor) map.
Since GlxGetXIDMap doesn't take a ClientPtr argument, GlxDispatchRequest will
store the client for the current request in a global variable. That way, the
ABI for GLXVND doesn't need to change.
v2: Fix an error check in GlxDispatchRequest.

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)
