Problem: Xdmx exit with error "(Fatal Error) dmx: Unknown input argument: "
if local input driver is specified (example: -input local,usb-kbd,usb-mou).

Cause: code block for remote input drivers is placed in code path common

4d53e30651 meson: Don't use '' in link_with, ever
String arguments as elements in the array passed to the link_with
argument in meson's executable() functions are not valid and will end up
causing the build file generation to file. This actually ended up
exposing a bug in meson that caused it not to report where in the
meson.build file it was failing:

https://github.com/mesonbuild/meson/pull/2527

The proper way to have a variable that can contain either an empty link
target or an actual link target is:

some_target = []
if some_cond
    some_target = static_library(...)
endif

This way if some_cond is False, some_target gets set to [], gets passed
to executable() in the link_with array, and then gets removed by array
flattening.

This also unbreaks Xwayland builds with -Dglx=false, the thing that
originally made me notice this.

1549e30372 Add a Meson build system alongside autotools.
This is a work in progress that builds Xvfb, Xephyr, Xwayland, Xnest,
and Xdmx so far.  The outline of Xquartz/Xwin support is in tree, but
hasn't been built yet.  The unit tests are also not done.

The intent is to build this as a complete replacement for the
autotools system, then eventually replace autotools.  meson is faster
to generate the build, faster to run the bulid, shorter to write the
build files in, and less error-prone than autotools.

v2: Fix indentation nits, move version declaration to project(), use
    existing meson_options for version-config.h's vendor name/web.

d13cb97442 ddx: add new call to purge input devices that weren't added
Special case for the systemd-logind case in xfree86: when we're vt-switched
away and a device is plugged in, we get a paused fd from logind. Since we
can't probe the device or do anything with it, we store that device in the
xfree86 and handle it later when we vt-switch back. The device is not added to
inputInfo.devices until that time.

When the device is removed while still vt-switched away, the the config system
never notifies the DDX. It only runs through inputInfo.devices and our device
was never added to that.

When a device is plugged in, removed, and plugged in again while vt-switched
away, we have two entries in the xfree86-specific list that refer to the same
device node, both pending for addition later. On VT switch back, the first one
(the already removed one) will be added successfully, the second one (the
still plugged-in one) fails. Since the fd is correct, the device works until
it is removed again. The removed devices' config_info (i.e. the syspath)
doesn't match the actual device we addded tough (the input number increases
with each plug), it doesn't get removed, the fd remains open and we lose track
of the fd count. Plugging the device in again leads to a dead device.

Fix this by adding a call to notify the DDX to purge any remainders of devices
with the given config_info, that's the only identifiable bit we have at this
point.

d206c240c0 configurable maximum number of clients
Make the maximum number of clients user configurable, either from the command
line or from xorg.conf

This patch works by using the MAXCLIENTS (raised to 512) as the maximum
allowed number of clients, but allowing the actual limit to be set by the
user to a lower value (keeping the default of 256).

There is a limit size of 29 bits to be used to store both the client ID and
the X resources ID, so by reducing the number of clients allowed to connect to
the X server, the user can increase the number of X resources per client or
vice-versa.

Parts of this patch are based on a similar patch from Adam Jackson
