A change during the 1.20 development cycle resulted in fbconfigs being walked
and deallocated individually during __glXScreenDestroy. This change
now avoids a use-after-free caused by that change.

There is a place where this code was called on the main thread.
We're using a rather nasty anti-pattern to just call a block inline rather
than synchonously calling it on the main thread if we're already on the main
thread. This code could use a good overhaul, but I don't have time to rip
it apart right now. This will address the immediate issue.

The big change here is MakeCurrent and context tag tracking. We now
delegate context tags entirely to the vnd layer, and simply store a
pointer to the context state as the tag data. If a context is deleted
while it's current, we allocate a fake ID for the context and move the
context state there, so the tag data still points to a real context. As
a result we can stop trying so hard to detach the client from contexts
at disconnect time and just let resource destruction handle it.
Since vnd handles all the MakeCurrent protocol now, our request handlers
for it can just be return BadImplementation. We also remove a bunch of
LEGAL_NEW_RESOURCE, because now by the time we're called vnd has already
allocated its tracking resource on that XID.
v2: Update to match v2 of the vnd import, and remove more redundant work
like request length checks.
v3: Add/remove the XID map from the vendor private thunk, not the
backend. (Kyle Brenneman)
v4: Fix deletion of ghost contexts (Kyle Brenneman)

Just never filled in, oops. Seems to have gone unnoticed because
normally glXQueryContext simply returns the values filled in by the
client library when the context was created. The only path by which you
normally get to a GLXQueryContext request is glXImportContext, and then
only if the context is already indirect.
However, that's a statement about Mesa's libGL (and anything else that
inherited that bit of the SGI SI more or less intact). Nothing prevents
a mischeivous client from issuing that request of a direct context, and
if they did we'd be in trouble because we never bothered to preserve the
associated fbconfig in the context state, so we'd crash looking up
GLX_VISUAL_ID_EXT. So let's fix that too.

This header is a truly ancient remnant of the SGI SI code, which used
the same struct for visual/fbconfig state on both sides of the wire.
We're not using this struct ourselves so let's stop depending on the
header.

Roundhouse kick replacing the various (sizeof(foo)/sizeof(foo[0])) with
the ARRAY_SIZE macro from dix.h when possible. A semantic patch for
coccinelle has been used first. Additionally, a few macros have been
inlined as they had only one or two users.
