Import patches-unapplied version 2.213 to ubuntu/utopic-proposed

Imported using git-ubuntu import.

Changelog parent: 0d33db8e8f

New changelog entries:
  * The EXTRA_ARCHIVES environment variable defined in 2.212 doesn't quite
    work properly because it doesn't allow for signing key configuration.
    Rename it to the more domain-specific EXTRA_PPAS (which is now a
    space-separated sequence of <ppa-owner>/<ppa-name> pairs), and fetch
    signing keys for those from Launchpad using python3-software-properties.
