Philipp Wiesemann e964d00f64 X11: Fixed SDL_GL_GetSwapInterval() returning -1 if interval is unknown. 
It should return 0 as a safe default if the interval can not be determined.

Ryan C. Gordon f5cf86769a x11: Catch fatal X errors when calling glXMakeCurrent(). 
In extremely rare cases, probably due to misconfigured drivers, one might
see this happen, and rather than terminate the process, we try to recover
by reporting an error to the app.

Fixes Bugzilla #3068.

Philipp Wiesemann 0e45984fa0 Fixed crash if initialization of EGL failed but was tried again later. 
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().
