[Mesa-dev] [PATCH] glx: do not leak the dri2 extension information

[Emil Velikov]

The XExtensionInfo is allocated dynamically (if the pointer is NULL)
in the XEXT_GENERATE_FIND_DISPLAY macro. On the other hand the
macro XEXT_GENERATE_CLOSE_DISPLAY does not check/free the memory.

Follow the example set by dri1 and appledri, and use a static variable.

Spotted while hunting "still reachable" leaks in Waffle.
