We'd like to avoid __glXInitialize as much as possible since it involves
taking a global lock. This means converting internal APIs to operate as
much as possible in terms of something other than a Display *, since if
that's all you have then you're forced to call __glXInitialize to get to
the glx_display.

This is a minor bugfix, in that the prior code required that the server
expose either XFree86-DRI or DRI2 to get the name; Xwayland exposed
neither, just DRI3. Now, for DRI2 and DRI3, we just ask the loader. It
also means we report "swrast" for the driver name when that's what we're
using, which is probably a good thing.

A number of internal VMware apitrace traces image comparisons fail with
dri3 because the viewport transformation becomes incorrect after an X
drawable resize. The incorrect viewport transformation sometimes persist
until the second draw-call after a swapBuffer.
Comparing with the dri2 glx code there are a couple of places where dri2
invalidates the drawable in the absence of server-triggered invalidation,
where dri3 doesn't do that. When these invalidation points are added to
dri3, the image comparisons become correct.

The GLX specification says about glXDestroyPixmap:
"The storage for the GLX pixmap will be freed when it is not current
to any client."
So arguably, functions like glXSwapIntervalMESA can be called after
glXDestroyPixmap has been called for the currently bound GLXPixmap.
In that case, the GLXDRIDrawable no longer exists, and so we just skip
those calls.
