The workQueue pointer is currently declared extern, so that WaitForSomething()
can check wether we've got something in the queue and call ProcessWorkQueue()
then.
But that's trivial to simplify: just let ProcessWorkQueue() return early if
workQueue == NULL. Gives us a better isolation of internal stuff as well as
ProcessWorkQueue() protecting itself from possible segfault.

AbortClient performs most of the same operations as
CloseDownFileDescriptor except that it doesn't call ospoll_remove,
leaving that unaware that the file descriptor has been closed.
If the file descriptor is re-used before the server comes back around
to clean up, and that new file descriptor is passed to SetNotifyFd,
then that function will mistakenly re-interpret the stale ClientPtr
returned by ospoll_data as a struct notify * instead and mangle data
badly.
To fix this, the patch does:
1) Change CloseDownFileDescriptor so that it can be called multiple
times on the same OsCommPtr. The calls related to the file
descriptor are moved inside the check for trans_conn and
oc->trans_conn is set to NULL after cleaning up.
2) Move the XdmcpCloseDisplay call into CloseDownFileDescriptor. I
don't think the actually matters as we just need to know at some
point that the session client has exited. Moving it avoids the
possibility of having this accidentally trigger from another client
with the same fd which closes down at around the same time.
3) Change AbortClient to call CloseDownFileDescriptor. This makes sure
that all of the fd-related clean up happens in the same way
everywhere, in particular ensures that ospoll is notified about the
closed file descriptor at the time it is closed and not some time later.

The type of fd_mask was changed in Cygwin 2.4.0 headers from 'long' to
'unsigned long'. This exposes an existing problem with winauth.c, which
includes Xwindows.h (which includes windows.h, which defines WIN32),
before including osdep.h, which causes the now conflicting definition of
fd_mask in osdep.h to be exposed:
In file included from ../os/osdep.h:198:18: error: conflicting types for
‘fd_mask’ typedef long int fd_mask; /usr/include/sys/select.h:46:23:
note: previous declaration of ‘fd_mask’ was here typedef unsigned long
fd_mask;
Adjust the include guards in osdep.h to make sure we only use WIN32
guarded code when not compiling for Cygwin (i.e. WIN32 && !__CYGWIN__)
This isn't a very elegant, but unfortunately appears to be the best
solution, since it doesn't seem to be possible to write the test in a
positive form.
Future work: Should also audit of all the other uses of WIN32 in
xserver, and make sure they are correct.

This provides a callback-based interface to monitor file
descriptors beyond the usual client and device interfaces.
Modules within the server using file descriptors for reading and/or
writing can call
Bool SetNotifyFd(int fd, NotifyFdProcPtr notify_fd, int mask, void *data);
mask can be any combination of X_NOTIFY_READ and X_NOTIFY_WRITE.
When 'fd' becomes readable or writable, the notify_fd function will be
called with the 'fd', the ready conditions and 'data' values as arguments,
When the module no longer needs to monitor the fd, it will call
void RemoveNotifyFd(int fd);
RemoveNotifyFd may be called from the notify function.

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
