  [ Chris Coulson ]
  * Refresh patches
    - update debian/patches/unity-menubar.patch
  * Disable ALSA backend for Firefox 55 because it makes the build failure.
    This will remain disabled until somebody steps up to maintain it
  * Fix a build failure in cubeb-pulse-rs on architectures where char is
    unsigned
    - add debian/patches/cubeb-pulse-rs-fix.patch
    - update debian/patches/series
  * Refactor nsNativeMenuService ownership and shutdown behaviour - the only
    reference to it now is held by the service manager, and the global instance
    pointer is no longer cleared during the xpcom-shutdown notification. This
    fixes a shutdown UAF that appeared in the current Firefox version, where
    nsWindow and the associated nsMenuBar can be destroyed after xpcom-shutdown,
    when it was too late to clean up properly.
    - update debian/patches/unity-menubar.patch
  * Hopefully fix LP: #1711337 by building the armhf build with
    -fno-schedule-insns to work around a compiler bug
  * Backport a couple of upstream breakpad-client fixes to unbreak the build
    with glibc 2.26
    - add debian/patches/use-ucontext_t-in-breakpad-client.patch
    - add debian/patches/use-ucontext_t-in-breakpad-client_2.patch
    - update debian/patches/series
