https://launchpad.net/bugs/274085
* Merge to Debian experimental, to get Ekiga 3. (LP: #274085) Remaining
  Ubuntu changes:
  - Launchpad Integration: (Ubuntu specific)
    + debian/control.in: Add liblaunchpad-integration-dev build dependency.
    + Add ubuntu_lpi.patch: Call launchpad_integration_add_items() in main() and
      check for the launchpad-integration pkg-config module.
    + Add autoconf.patch: autoconf changes from above patch.
  - Add ubuntu_desktop-file-onlyshowin.patch: Show ekiga in Mobile, too.
    (Ubuntu specific).
  - debian/control.in: Add missing fdupes build dependency for identical
    GNOME help file symlinking. (Debian #505536)
* Drop 42_change_pixmaps.dpatch: Many of the old icons do not exist any
  more, some have been replaced, and keeping the remaining three would make
  them look very inconsistent.
* Convert our dpatches to quilt patches and rewrite them for new upstream
  version.
* Add migrate_2.0_settings.patch: Properly migrate settings from
  2.0. Taken from upstream SVN, thanks to Damien Sandras!
