Comment 1 for bug 1320422

This merge is useful because it brings us much closer to the Debian
package. Some notable changes with the new package:

 - Adds autopkgtests for dbus
   + Previously disabled Build-Depends used for testing are now enabled
 - A new dbus-run-session program that allows one to start a new session
   and run a program in that session
 - Built against libaudit, so system bus AppArmor denials will go to the
   audit log if auditd is installed and running
   + Otherwise, all AppArmor denials will continue going to the syslog
   + All session bus denials will continue to go to the syslog due to
     the session bus not having sufficient privs to write to the audit
     log
 - There's a new org.freedesktop.DBus.GetConnectionCredentials bus
   method that provides a single call to get all of the credentials for
   a connection.
 - I refreshed the AppArmor mediation patches using the v3 patches from
   the upstream bug
   + https://bugs.freedesktop.org/show_bug.cgi?id=75113
   + I think these are fairly close to going in upstream so I hope we
     won't have to carry them much longer
   + These patches include support for sticking the AppArmor confinement
     context in the return value of
     org.freedesktop.DBus.GetConnectionCredentials
 - The upstream NEWS file has all of the gory details
   + http://dbus.freedesktop.org/doc/NEWS

I've tested this debdiff in the following ways:
 - Running QRT's test-dbus.py script in a clean Utopic amd64 VM
 - Running the new autopkgtests in a clean Utopic amd64 schroot
 - Manual exploratory testing in a clean Utopic amd64 VM
