Xnest: add helper for retrieving GC XID on upstream connection
...
Upcoming patches will need to retieve GC's XIDs on the upstream connection.
Moving this out into separate .c file, in order to not creating more
dependencies on Xlib headers, which we wanna get rid of.
For now, looking at the Xlib GC structure, attached to our DDX GCs.
When all users of the Xlib GC have gone (ie. moved all consumers to xcb),
we'll create the GC via xcb directly, thus replacing the Xlib GC struct
by XID - the interface of this helper will remain the same.

...
In order to transition to XCB, we need to link xcb, but temporarily
also x11-xcb.

xfree86: common: use LogMessageVerb() instead of xf86Msg()
...
Both are doing same job, so no need to keep using an duplicated implementation.

os: log: drop now meaningless XLOG_FLUSH option
...
Since we're not indirectly writing via FILE anymore, this option has
become meaningless: it meant flushing out our in-process buffer to
the kernel, but we're now doing direct write() calls anyways.
xf86 still accepts the "flush" config file flag for backwards compatibility,
but it hasn't any practical meaning anymore.

xkb: unexport DDX entry points
...
These functions are entry points of the DDX (or stubs thereof), not supposed
to be called by any drivers, so no need to keep them exported.

xkb: unexport internal variables
...
These aren't used by any drivers/modules, and it doesn't seem make much
sense doing so, thus no need to keep them exported.

os: unexport xstrtokenize()
...
Not used by any external drivers/modules, so no need to keep it public.
Since modesetting is using it, still needs _X_EXPORT, as long as it's
a module.

xwayland: replace xallocarray() by calloc()
...
Only key difference that calloc(), in contrast to rellocarray(),
is zero-initializing. The overhead is hard to measure on today's
machines, and it's safer programming practise to always allocate
zero-initialized, so one can't forget to do it explicitly.
