[PATCH] Replace libx11 by libxcb

[Simon McVittie]

Could you attach (a revised version of) this to a freedesktop bug if you
haven't already, please?

I don't speak X11, so I haven't reviewed the C, but here are some fixes for
the autofoo:

More portable to deficient shells as:

    test x$enable_x11 = xyes || test x$enable_x11 = xauto

The second condition isn't checked: it's passed as an argument to true(1) or
false(1). I think you meant:

    if ! $have_xcb && test x$enable_x11 = xyes; then

This needs the same change.

Again, the second condition isn't checked. I think you meant:

    if $have_xcb && $have_xcb_aux; then
