Add support for EGL_KHR_get_all_proc_addresses

Browse Source 
If EGL_KHR_get_all_proc_addresses extension is supported, then don't try
to load a separate client library. Instead, just use eglGetProcAddress
to load everything.

This can also avoid problems with trying to use OpenGL functions from
libGL.so.1 (which is the GLX library) when an EGL context is current.

Closes #871.
