In order to get away from wrapping ScreenRec proc vectors, it's necessary to
some API for pixmap consumers, which they can use for creating or destroying
them, so they don't need to call the ScreenProc vectory directly anymore.

The code is easier to understand when variables are declared where they're
used for the first time, scoped to where they're needed and not reused
for separate things.

If DRI2ScreenInit hasn't been called yet, DRI2Authenticate and
DRI2CreateDrawable2 cause the X server to crash. This has been observed
to happen on multiple modern Linux distros in various conditions,
including QEMU and VMware VMs. Make these functions more robust in order
to prevent the crash.
This patch was originally provided by Bernhard Übelacker and expanded
upon by Mark Wagner.

Right now, we're only registering the depths of our visuals, which are
mirroring upstream's visuals. But forgotten to register the pixmap depths
that don't have an assiocated visual.

This new lookup function retrieves a pointer to WindowRec structure by
associated XID. Unlike dixLookupWindow(), this one works globally, instead
of just on one specific client, and it doesn't do any XACE calls.

The old PCCONS driver only seems to be used on minimal install disks and
cannot coexist with newer ones, so there's probably no practical use case for
supporting it in Xorg anymore.

arc4random_buf() is a pretty standard libc function on Unix'oid platforms,
but not all our targets have it, thus we need a fallback there. Currently we
have GenerateRandomData(), which either just wraps arc4random_buf() or provides
some fallback implementation.
For those cases it's easier to just implement missing functions directly
instead of having custom wrapper functions. So, drop GenerateRandomData()
in favor of arc4random_buf() and provide fallback implementation for where
it is missing.

(submit/cursor-api) dix: drop superfluous XineramaGetCursorScreen()
It's only used for record extension, no external callers, thus doesn't
need to be exported. Since it's just for retrieving one struct value,
it's not needed at all - we can do this directly (just like we do in
many other places)
Note: the check on noPanoramixExtensions is superfluous, since the only
call site already does it.

We already have our own signal safe vnsprintf() implementation, which is used
for formatting log messages while being in a signal handler, there's no need
to have two separate implementations of all the logging functions.

Simplify log formatting functions and remove redundancies, e.g.:
* common function for line termination
* copy prefix directly instead of *printf'ing it
* now just exactly one LogSWrite() call per message
(good for other log targets like syslog)

This allows us to do further probing in the included meson files:
Individual subdirectories (eg. DDXes, extensions, OS layer, ...)
can now probe things that are only relevant to them - no need to fill
the already too fat includes/meson.build with even more things.
Preparation for upcoming commits that'll make us of that.

No need for extra call to some demuxer function for nothing but setting a

writing some value into a variable, so it's trivial to just to do that, instead
of having an unncessarily complex "universal setter" for that.

Both xlib as well as the Xserver use the same identifier "GC" for
different types. While on xlib it's just the numerical ID of a GC,
the xserver defines a struct for it by the same name. This is this
ugly and needs ridiculous hacks for Xserver code that needs xlib.
Easy to solve by just renaming the GC typedef to GCRec (consistent
with how we're naming other structs) and replacing GC* by GCPtr.

DEV_MEM define isn't used by any drivers, and BSD seems to be the only
platform using /dev/pmem instead of /dev/mem - as well as the DEV_MEM
define from xf86_OSlib.h (Linux uses the symbol, but defines on its own)
Therefore, just define it where actually used and drop it from the global
xf86OSlib.h file.
Note that /dev/pmem refers to physical memory, not to be mixed up with
Linux's persistent memory subsys, which uses /dev/pmem[N] device nodes.
