[PATCH xserver 3/3] xwayland: Add glamor egl_backend for EGLStreams

[Mario Kleiner]

Mini bug report:

My build of server 1.20-rc5 now fails on Ubuntu 16.04 due to lack of
epoxy_has_egl():

  CC       Xwayland-xwayland-glamor.o
xwayland-glamor.c: In function ‘xwl_glamor_egl_supports_device_probing’:
xwayland-glamor.c:58:12: error: implicit declaration of function
‘epoxy_has_egl’ [-Werror=implicit-function-declaration]
     return epoxy_has_egl() &&
            ^
xwayland-glamor.c:58:5: warning: nested extern declaration of
‘epoxy_has_egl’ [-Wnested-externs]
     return epoxy_has_egl() &&
     ^
cc1: some warnings being treated as errors


Apparently libepoxy v1.4.0 or later is required to build now with that
function defined, so that needs some fix or version check.

Cheers,
