FFE: xcb-proto/libxcb 1.13

[Timo Aaltonen]

This will be needed for the first HWE stack in 18.04.2, so best to add them now and not as an SRU which will be more painful.

xcb-proto
Release 1.13 (2018-02-28)
=========================
* dri3: Add multi-plane/modifier protocol for v1.2
* present: Add suboptimal-copy protocol for v1.2
* randr: Add output-lease protocol for v1.6
* Add support for variable-sized lists of FDs
* xge: Add safe generic-event sending support
* Fix initial connection handshaking
* Updated XML DTD
* Python 3.x cleanups and compatibility

libxcb
Release 1.13 (2018-02-28)
=========================
* Add support for variable-sized lists of FDs
* Poll for events when blocking waiting for special events
* xinput: Enable XInput extension by default
* ge: Add explicit support for GenericEvent extension
* Fix documentation warnings from clang
* Cosmetic cleanups

although it's hard for me to prove, but libxcb should fix a number of threading issues seen in the past.

These are already in Debian testing, so they build and haven't caused regressions.
