[build] Spring cleanup of configure.ac

Let's try to bring configure.ac into this century, shall we?

* Use the proper shell macros AS_IF and AS_CASE instead of if...fi
  and case...esac

* Check for X11 and relative extensions only when building for GLX
  and EGLX backends

* Add documentation on the behaviour of binary_age and interface_age

* Coalesce all the common checks to avoid redundancy

* Escape everything that requires escaping
