Subject: [PATCH] local-display-factory: Don't try to respawn displays on
shutdown
At the moment in the shutdown path we may try to respawn displays
that just got killed.
The respawning happens when things are half torn down leading to
crashes.
This commit makes sure we turn off the respawn logic in the shutdown
path.

Subject: [PATCH 3/3] xdmcp-display-factory: Set supported session types for
XDMCP displays
The lower levels of GDM now expect the session types supported by a
display to be specified up front.
This commit makes sure XDMCP displays do that.
