X11: Fix previous error handler not being restored

Browse Source 
GLFW did not restore the previous Xlib error handler when removing its
own, instead resetting to the default handler.

This commit saves and restores the previous error handler.

None of this is thread-safe or could ever be.

Fixes #2108
