[Xcb] when to do a new libxcb release

[Alan Coopersmith]

There's also a backlog of patches awaiting review/applying both on
the list and in bugzilla:

https://bugs.freedesktop.org/buglist.cgi?product=XCB&keywords=patch&resolution=---

Unfortunately, http://patchwork.freedesktop.org/ doesn't seem to be
configured to suck in patches from the xcb mailing list, so more manual
methods would be needed to find the outstanding patches there.
