dri: Extend __DRIbackgroundCallableExtensionRec to include a callback that checks for thread safety

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

When glthread is enabled, the driver runs mostly on a separate thread.
Therefore we need to guarantee the thread safety between libX11 calls
from the applications (not aware of the extra thread) and the ones from
the driver.

See discussion thread:
   https://lists.freedesktop.org/archives/mesa-dev/2017-April/152547.html

Fortunately, Xlib allows to lock display to ensure thread safety but
XInitThreads must be called first by the application to initialize the lock
function pointer. This patch will allow to check XInitThreads was called
to allow glthread on GLX or EGL platform.

Note: a tentative was done to port libX11 code to XCB but it didn't solve fully
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."
