Check for integer overflow before using stuff->count in a multiplication,
to avoid compiler optimizing out due to undefined behaviour, but only

Atom is unfortunately unsigned long or unsigned int depending on the

The library used by the Xserver to read and parse the configuration file
could be built so that it culd be installed as a separate lib and used
by external programs.
Apparently there has not been any interest in this for quite a while as
this library has been broken for a long time now in the sense that it
was calling functions provided by the Xserver which were not implemented
for the external library.
Since this library is useless as it is anyway when built let's drop
support for it.

The X server frequently deals with SIGIO and SIGALRM interruptions.
If process execution is inside certain blocking system calls
when these signals arrive, e.g. with the kernel blocked on
a contended semaphore, the system calls will be interrupted.
Some system calls are automatically restartable (the kernel re-executes
them with the same parameters once the signal handler returns) but
only if the signal handler allows it.
Set SA_RESTART on the signal handlers to enable this convenient
behaviour.

Commit 2172714c changed behavior of capability handling, but it only
solved part of the problem. If Xwayland is launched without a capability
(e.g. no pointer device is connected when Xwayland was spinned up), and
later that capability comes, the device added will not be automatically
initialized. This patch initializes the device when the capability is
reported for the first time, thus avoiding the problem.

This was built as a hack for simple Wayland compositors like Weston
which were lazy and didn't want to configure windows server-side when
moved.
Since comboboxes and menus are separate toplevel O-R windows, this hack
breaks input as it needs to be traced normally, not simply sent to the
focused window.
X11 toolkits really do need their windows to be configured correctly
for their O-R windows comboboxes or menus other things, so let's fix
the lazy compositors and remove this.
I have tested this patch with both Weston and Mutter and neither of
them require any changes, and it fixes comboboxes and menus.
If somebody then wants to revert 73698d4, that's fine by me, so we
reduce the amount of API that DDXen have.

A user on a nouveau-driven card ran into a problem where DVI-D-1 and
DVI-I-1 were aliasing. The simplest fix is to provide the full connector
names. While we're at it, rename the output names to match what is in
the kernel, and start counting the connectors from 1 rather than 0. The
only deviation is HDMI vs HDMI-A, which kept its original name.
This will break backwards compatibility with existing xorg.conf's that
reference output names, but the alternative is to create a separate
counting system, further disconnecting from the kernel names.

Make the maximum number of clients user configurable, either from the command

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.
