egl: move unofficial extensions to eglmesaext.h

As suggested by Ian in

  http://lists.freedesktop.org/archives/mesa-dev/2011-December/016035.html

Note that eglext.h has to include eglmesaext.h at the end instead of the
beginning because some extensions in eglmesaext.h depend on the official
extensions.
