* Merge with Debian, bringing in a new upstream and many small fixes:
  - patches/any/cvs-malloc-deadlock.diff: Dropped, merged upstream.
  - patches/ubuntu/lddebug-scopes.diff: Rebase for upstream changes.
  - patches/ubuntu/local-CVE-2012-3406.diff: Rebased against upstream.
  - patches/ubuntu/no-asm-mtune-i686.diff: Fixed in recent binutils.
* This upstream merge fixes a nasty hang in pulseaudio (LP: #1085342)
* Bump MIN_KERNEL_SUPPORTED to 2.6.32 on ARM, now that we no longer
  have to support shonky 2.6.31 kernels on imx51 babbage builders.
* Drop patches/ubuntu/local-disable-nscd-host-caching.diff, as these
  issues were apparently resolved upstream a while ago (LP: #613662)
* Fix the compiled-in bug URL to point to launchpad.net, not Debian.
