2.13.0.8 stuff:

- Because the main gdm.conf file is now read-only, contains distro
  defaults and is not to be edited by the user, the file has been
  moved to ${datadir}/gdm/defaults.conf (also factory-gdm.conf is
  now %{datadir}/gdm/factory-defaults.conf).  Users can use the
  --with-defaults-conf to specify the location of this file.
  Note that this means that distributions who want to preserve GDM 
  configuration set by those using older versions of GDM should use
  preinstall/postinstall scripts to move the /etc/gdm/gdm.conf file
  to /etc/gdm/gdm.conf-custom if the file has been edited (compare
  against /etc/gdm/factory-gdm.conf to see if it has been modified).
  "make install" for GDM does this if building from source.  GDM
  docs updated to reflect this change.

- Lots of performance issues with the GDM sockets connection improved.
  Now the code deals much better with failures, and better debug is
  printed to the log.

- Improved debug logic in GDM slaves so they use common functions.

- Fix gdmdynamic so it supports up to hundreds of displays rather than
  just a dozen or so.  Now gdmdynamic backs off on sending sockets
  commands to the server if it is being flooded with requests.  Added
  new "SERVER_BUSY" sockets command to support this feature and new
  -t and -s command line options so the back-off behavior can be 
  tuned, if needed.

- The config logic for the slaves will now return the compiled in
  value if it fails to connect to the server for better behavior.

- gdm-restart, gdm-safe-restart, gdm-stop, and gdm.spec now use
  gdmflexiserver to get config data rather than trying to grep and 
  awk the config file directly.  

- Fix Xsession script so zenity calls work.

- Lots of improvements to the GDM docs.  Added section about "PAM" in
  Security.  Add comment that +xkb is needed for keyboard gesture
  listeners (accessibility) to work.  Also updated README and 
  README.install and moved some information that was in these files
  to the docs.

- Bump MAX_CONNECTIONS from 10 to 15 so that the daemon will accept
  more connections from slaves.  This improves performance when the
  daemon is flooded with requests.

- Fix include statement in daemon/gdmconfig.c to fix compile problem
  on LFS.
