Request-handlers as registered in the requestVector array, always get
passed the clientPtr for the client which sent the request.
But the implementation of many request-handlers typically consists of
a generic handler calling implementation specific callbacks and / or
various helpers often multiple levels deep and in many cases the clientPtr
does not get passed to the callbacks / helpers.
This means that in some places where we would like to have access to the
current-client, we cannot easily access it and fixing this would require
a lot of work and often would involve ABI breakage.
This commit adds a GetCurrentClient helper which can be used as a
shortcut to get access to the clienPtr for the currently being processed
request without needing a lot of refactoring and ABI breakage.
Note using this new GetCurrentClient helper is only safe for code
which only runs from the main thread, this new variable MUST NOT be used
by code which runs from signal handlers or from the input-thread.
The specific use-case which resulted in the creation of this patch is adding
support for emulation of randr / vidmode resolution changes to Xwayland.
This emulation will not actually change the monitor resolution instead it
will scale any window with a size which exactly matches the requested
resolution to fill the entire monitor. The main use-case for this is
games which are hard-coded to render at a specific resolution and have
sofar relied on randr / vidmode to change the monitor resolution when going
fullscreen.
To make this emulation as robust as possible (e.g. avoid accidentally scaling
windows from other apps) we want to make the emulated resolution a per client
state. But e.g. the RRSetCrtc function does not take a client pointer; and is
a (used) part of the Xorg server ABI (note the problem is not just limited
to RRSetCrtc).

When building Xwayland with neither DRI nor GLamor support enabled with

libdrm and epoxy even though those are not used/needed.
Make sure we require and link against libdrm and epoxy only if needed.

I don't think an input thread can ever be useful on Windows.
There is a pthread emulation, so having the thread itself isn't much of
a problem.
However, there is no device to wait on for Windows events, and even if
we were to replace select() with WFMO, Windows wants to send events for
a window to the thread which created that window.
So, disable input thread by default for MinGW
v2:
Also add similar to meson.build
Add a new function, GlxServerExports::setClientScreenVendor, which will change
the vendor that handles GLX requests for a screen, but only for requests from

Differences from autotools:
* Autotools defined NO_ALLOCA for OSX builds. I don't think we need
this anymore as Xalloc.h is no longer used anywhere in the xserver.
* X11.bin is linked with -u,miDCInitialize, and then libserver_mi
provided to satisfy (just) that. It's been that way since the commit
which added it. We can't write the equivalent in meson due to linker
argument ordering issues, but do we really need to?
* An explicit -Dsecure-rpc=false is required for OSX, since in meson we
don't do the checks that XTRANS_SECURE_RPC_FLAGS did for the existence
of the specific RPC functions required.

MinGW-w64 gcc has a built-in strndup, but it's not in the C library and
MinGW-w64 headers don't prototype it.
Don't try to use it, as that will cause an undefined reference if gcc
decides that an out-of-line call is appropriate.
Currently, this can error if dri.pc isn't found, as we can't then get
the value of pkgconfig variable from it:
include/meson.build:199:10: ERROR: 'dri' is not a pkgconfig dependency
I think we need DRI_DRIVER_PATH (only) when building GLX, even if dri2/3
isn't enabled, so we know where to load swrast_dri.so from.
(For autotools, configure.ac directly calls `pkg-config
--variable=dridriverdir dri`, the backticks swallowing any error,
causing the value of this define to be empty if dri.pc isn't present)
It doesn't require shared memory dir and thus allows
to avoid cases when this dir is detected incorrectly,
as in https://bugreports.qt.io/browse/QTBUG-71440

If the server resets, most client workqueues are cleaned up as the
clients are killed.
The one exception is the server's client, which is exempt from
the killing spree.
If that client has a queued work procedure active, it won't get
cleared on reset.
This commit ensures it gets cleared too.
glibc 2.25 has dropped sys/sysmacros.h from sys/types.h, so add
it explicitly in config/udev.c.

___CLIENTSIGNAL_DEFINED___ is a hack to work around the declaration of
ClientSignal both in our own headers and in <X11/include/fontproto.h>,
the latter of which is properly part of libXfont (1, only) but packaged
in xorgproto because we have made some mistakes. ClientSignalAll needs
no such workaround.

The autoconf build hard-codes XCONFIGFILE to just 'xorg.conf':
XF86CONFIGFILE="xorg.conf"
AC_DEFINE_DIR(XCONFIGFILE, XF86CONFIGFILE, [Name of configuration file])
Later, the X server passes that into DoSubstitution() which expands the path:
DoSubstitution(template="/etc/X11/%X", ..., XConfigFile="xorg.conf")
This returns "/etc/X11/xorg.conf".
The Meson build, on the other hand, sets XCONFIGFILE to
join_paths(get_option('sysconfdir'), 'xorg.conf'). If sysconfdir is /etc, this
results in '/etc/xorg.conf', resulting in DoSubstitution returning
'/etc/X11/etc/xorg.conf'.
Fix this by just hard-coding XCONFIGFILE to 'xorg.conf'.
