GDM miscounts current sessions

* Sun Feb 01 2004 Warren Togami <wtogami redhat com> 1:2.4.4.5-8
- patch30 xdmcp_session counter fix from gdm-2.5.90.0 #110315
- automake14 really needed, not automake
- BR libcroco-devel, libcroco-devel, libattr-devel, gettext
- conditionally BR libselinux-devel
- explicit epoch in all deps

gdm-2.x from FC1 and FC2 rawhide fail to properly count the number of 
concurrent XDMCP sessions.  Rather than a maximum simultaneous sessions 
counter, MaxSessions parameter became a maximum number of sessions 
forever counter.

The original code LOOKS correct, but gdm-2.5.90.0 hints to a race 
condition that could be causing this behavior.  I copied the code from 
gdm-2.5.90.0 into rawhide's gdm and it seems to work.  The spec patch 
also contains explicit BuildRequires fixes and versioned-dep-epochs.

Please verify that the patch solves the problem without introducing any 
regressions.  A redone package will need to go into FC1 updates/testing 
soon too, especially for the K12LTSP folks.

If these changes look good, I ask that Havoc check them into rawhide 
ASAP.  It should not be too late to make FC2 test1 (I hope especially 
since changeloop is still broken.)
