X11: Don't create a window and GL context to look up the glX extension string.
It's not necessary.

glX HasExtension(): check for NULL ext string first.
It's slightly faster than failing later, after a strchr() call, since this
will get called multiple times with a NULL string if the system totally
fails elsewhere.

X11: Fixes for OpenGL 3.0 and later context creation.
- Don't create a temporary context first; this was probably due to Windows
needing one to get the address of wglCreateContextAttribsARB(), but that's
a unique quirk of WGL, and doesn't apply to glX. The glX spec explicitly says
you have to get a function pointer that works with any context from
glXGetProcAddress(), including when no context exists.
- Properly check for the GLX_ARB_create_context instead of just looking for a
non-NULL glXCreateContextAttribsARB()...some implementations, like Mesa,
never return NULL for function lookups (Mesa returns pointers into a jump
table that is filled out when the GL is initialized; since you can look up
functions before you have a valid context, it can't definitely say a function
isn't valid at that point).

Fixed bug 2802 - [patch] Fix android build compiling in wrong filesystem implementation
Jonas Kulla
The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c.
I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along.
