This code was broken anyway. Note that DEVICE_OFF would make dmx think
_no_ devices were using SIGIO anymore, which means 'xinput disable' on
your mouse would probably do weird things to your keyboard too. Rather
than try to repair that and keep SIGIO working on this one niche DDX,
just rip it out and use the thread model like everyone else.

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.

This is entirely accurate, albeit curiously phrased: swapping some bits
hanging off the end of a null pointer will make Xdmx crash, so from the
perspective of code generation the function will indeed not return.

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
