[ Tollef Fog Heen ]
* New upstream version.
  - Backport 3492207: journal: PAGE_SIZE is not known on ppc and other
    archs
  - Backport 5a2a2a1: journal: react with immediate rotation to a couple
    of more errors
  - Backport 693ce21: util: never follow symlinks in rm_rf_children()
    Fixes CVE-2012-1174, closes: #664364
* Drop output message from init-functions hook, it's pointless.
* Only rmdir /lib/init/rw if it exists.
* Explicitly order debian-fixup before sysinit.target to prevent a
  possible race condition with the creation of sockets.  Thanks to
  Michael Biebl for debugging this.
* Always restart the initctl socket on upgrades, to mask sysvinit
  removing it.

[ Michael Biebl ]
* Remove workaround for non-interactive sessions from pam config again.
* Create compat /dev/initctl symlink in case we are upgrading from a system
  running a newer version of sysvinit (using /run/initctl) and sysvinit is
  replaced with systemd-sysv during the upgrade. Closes: #663219
* Install new man pages.
* Build-Depend on valac (>= 0.12) instead of valac-0.12. Closes: #663323
