        This patch resolves some performance issues that I noticed when
        testing GDM with the gdmdynamic command.  I notice that waiting for
        the sockets to timeout made gdmdynamic slower so now all the clients
        load all the configuration data in one quick pass and close the
        socket.  Since the gdm_config_get functions cache the data, the slaves
        will not go over the socket to get the data again unless asked to
        reread.  Bump the maximum messages over the socket from 20 to 80
        because gdmlogin pulls about 65 configuration parms over and this
        allows all data to be accessed in one connection (and gives a little
        room for growth).  Improved the way GDM slaves deal with syslog so all
        slaves use the same interfaces.  Added three missing keys to the daemon
        configuration handling code.

        * daemon/gdmconfig.c: Add three keys that were missing for background
          program support.
        * gui/gdmcomm.[ch]: Now if there is a failure connecting to the daemon,
          the slave will sleep 1 second before retry (normally retries 5
          times).  If all retries fail, it will not try sleeping on subsequent
          calls to the daemon.  This greatly improves performance when the
          daemon is flooded with slave requests.  In normal usage, this will
          likely not happen, but it is good for GDM to not fail so easily.
          Added better debug.  Added gdm_comm_close function so that slaves
          can ask to close the socket when done reading config.  Now uses
          common syslog functions.
        * daemon/gdm.h: Add better comments, rename GDM_SUP_MAX_CONNECTIONS
          to GDM_SUP_MAX_MESSAGES which is more accurate, and bump the max
          number to 80.
        * gui/gdmcommon.h, gui/gdmwm.h, gui/gdmsession.h: Added common syslog
          functions to gdmcommon.h and moved some functions that were in
          gdmcommon.h to gdmwm.h and gdmsession.h since the implementations
          were in those c-files.  Renamed functions to make naming consistant.
        * gui/gdmXnestchooser, gui/gdmchooser.c, gui/gdmcommon.c,
          gui/gdmconfig.c, gui/gdmdynamic.c, gui/gdmflexiserver.c,
          gui/gdmlogin.c, gui/gdmphotosetup.c, gui/gdmsession.c, gui/gdmwm.c,
          gui/greeter/greeter.c, gui/greeter/greeter_item_ulist.c,
          gui/greeter/greeter_session.c, gui/greeter/greeter_system.c:  Slaves
          close sockets connection when done reading config.  Now slaves use
          common syslog functions.  Naming changes to reflect renaming of
          functions in gdmcommon.h/gdmwm.h/gdmsession.h.  Better debug.
        * daemon/auth.c, daemon/cookie.c, daemon/display.c, daemon/gdm.c,
          daemon/gdm-net.c, daemon/misc.c, daemon/slave.c, daemon/xdmcp.c,
          gui/gdmlanguages.c, gui/greeter/greeter_canvas_item.c,
          gui/gdmsetup.c, vicious-extensions/ve-config.c: Make spacing around
          "++" more consistant.  Add better debug in some functions
