When checking whether GLX or EGL are available on the system, we don't want to use the internal API that forces an exit() on missing libraries and symbols — as that would defeat the point. Instead, we should have safe functions to call internally that simply return a NULL pointer, so we can bail out ourselves in a controlled fashion.
Libraries and applications that depend on Epoxy currently have no way to safely degrade functionality if they are used on a platform without GLX support; the only way to achieve that is to perform a symbol check themselves, by essentially copying what Epoxy already does. By exposing `epoxy_has_glx()`, those libraries and applications now have the chance of querying Epoxy itself and gracefully handle failure.
Similar to `epoxy_has_glx()`, but for the EGL windowing system API.
