A new --with-fallback-input-driver=foo option allows selecting a
fallback driver for the server if the driver configured for the device
is not found. Note that this only applies when the device has a driver
assigned and that module fails to load, devices without a driver are
ignored as usual.
This avoids the situation where a configuration assigns e.g. the
synaptics driver but that driver is not available on the system,
resulting in a dead device. A fallback driver can at least provides some
functionality.
This becomes more important as we move towards making other driver true
leaf nodes that can be installed/uninstalled as requested. Specifically,
wacom and synaptics, a config that assigns either driver should be
viable even when the driver itself is not (yet) installed on the system.
It is up to the distributions to make sure that the fallback driver is
always installed. The fallback driver can be disabled with
--without-fallback-input-driver and is disabled by default on non-Linux
systems because we don't have generic drivers on those platforms.
Default driver on Linux is libinput, evdev is the only other serious
candidate here.

By default the X server will try CLOCK_MONOTONIC_COARSE before
CLOCK_MONOTONIC, while A Wayland compositor may only support getting
their timestamps from the CLOCK_MONOTONIC clock. This causes various
issues since it may happen that a timestamp from CLOCK_MONOTONIC
retrieved before a sending an X request will still be "later" than the
timestamp the X server than gets after receiving the request, due to the
fact that CLOCK_MONOTONIC_COARSE has a lower resolution.
To avoid these issues, make Xwayland always use CLOCK_MONOTONIC, so
that it becomes possible for Wayland compositor only supporting
CLOCK_MONOTONIC and X server to use the same clock.

The current SIGIO signal handler method, used at generation of input events,
has a bunch of oddities. This patch introduces an alternative way using a
thread, which is used to select() all input device file descriptors.
A mutex was used to control the access to input structures by the main and input
threads. Two pipes to emit alert events (such hotplug ones) and guarantee the
proper communication between them was also used.

The configure script looks for the libsystemd-daemon pkg-config
module. If the configure script finds it, the script will add
libsystemd-daemon to a list of modules which are used to consolidate
CFLAGS and LIBS.
The check for libsystemd-daemon was altered to fallback to libsystemd
if libsystemd-daemon was not found (libsystemd-daemon was brought into
libsystemd). Unfortunately, the configure script still adds
"libsystemd-daemon" to the list of modules to consolidate, instead of
"libsystemd". With this patch, we set a variable depending on which
pkg-config module is found and add that to the module list instead.
Changes since v1:
- Rearranged logic so that we do a versioned check for libsystemd
first, then look for libsystemd-daemon.
- Cleaned up the check a bit, only performing the module checks if we
don't have --with-systemd-daemon=no, in a similar style to
--with-dtrace.
- Changed the variable name to LIBSYSTEMD_DAEMON as per feedback.

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

If the suid wrapper is enabled, /usr/bin/Xorg is just a shell script that
execs either /usr/libexec/Xorg.bin directly or the Xorg.wrap binary which then
execve's /usr/libexec/Xorg.bin.
Either way, we end up with Xorg.bin, which is problematic for two reasons:
* ps shows the command as Xorg.bin
* _COMM and _EXE in systemd's journal will both show Xorg.bin as well
There's not much we can do about the path, but having the actual command stay
as Xorg means better compatibility to existing scripts. And, the reason for
this path: the command
journalctl _COMM=Xorg
works universally, regardless of whether the wrapper is used or not.
