DRI-drivers could call Xlib functions, for example to allocate a new back

When glthread is enabled, the driver runs mostly on a separate thread.
Therefore we need to guarantee the thread safety between libX11 calls

See discussion thread:

thread safety.
See discussion thread:
   https://lists.freedesktop.org/archives/mesa-dev/2017-April/153137.html

Note: Nvidia forces the driver to call XInitThreads. Quoting their manpage:
"The NVIDIA OpenGL driver will automatically attempt to enable Xlib
thread-safe mode if needed. However, it might not be possible in some
situations, such as when the NVIDIA OpenGL driver library is dynamically
loaded after Xlib has been loaded and initialized. If that is the case,
threaded optimizations will stay disabled unless the application is
modified to call XInitThreads() before initializing Xlib or to link
directly against the NVIDIA OpenGL driver library. Alternatively, using
the LD_PRELOAD environment variable to include the NVIDIA OpenGL driver
library should also achieve the desired result."

Strictly speaking __DRI_DRI2 implies __DRI2_FLUSH. Although since we're

gbm: manage only the required set of DRI extensions

Currently GBM attempts to know all the extensions that might be required
by EGL/DRM [at some later stage].

That is a bit unclear and we often forget to update GBM as EGL gets
attention.

To avoid that, simply let EGL manage it's own required extensions based
on the base primitive (screen) we provide it.

v2: Rework the approach - GBM should not dive into EGL/DRM.

Split the create_screen into:

This will allow us to reuse the latter two on egl/drm. Said platform
does create its own screen and attempts to reinvent the later two
functions itself.

Since the GBM ones tend to get out of sync quite often, and there is no
distinct reason why it does so we'll drop them with latter commits.
