Libraries like Xlib, some XCB language bindings, and potentially others
have a common problem: they want to share the X connection with XCB. This
requires coordination of request sequence numbers.  Previously, XCB had an
Xlib-specific lock, and allowed Xlib to block XCB from making requests.
Now we've replaced that lock with a handoff mechanism, xcb_take_socket,
allowing external code to ask XCB for permission to take over the write
side of the socket and send raw data with xcb_writev.  The caller of
xcb_take_socket must supply a callback which XCB can call when it wants
the write side of the socket back to make a request.  This callback
synchronizes with the external socket owner, flushes any output queues if
appropriate, and then returns the sequence number of the last request sent
over the socket.

Handoff mechanism inspired by Keith Packard.

External APIs that used 32-bit sequence numbers continue to do so.

This allows optimizing adjacent pending replies with the same flags, and
will help support default flags for a range of future requests.

These functions are once again a single pthread call, so just make that
call directly.

The GNU/kFreeBSD (and BSDs in general) have a different
layout of struct sockaddr, sockaddr_in, sockaddr_un ...

The first member do not have to be "sa_family",
they also have "sa_len" field.

GenericEvent can be more than 32 bytes long. Ensure that the required data is
pulled off the wire and tack it onto the event.

Due to the structure of the xcb_generic_event_t, the data is appended AFTER
the full_sequence field.

Hence, it is not necessary to explicitly add them to EXTRA_DIST.

making each extension library individually selectable for build.
