https://launchpad.net/bugs/600501
* Merge with Debian experimental; remaining changes:
  - debian/control: explicitly Conflicts with modemmanager: having both
    installed / running at the same time causes issues causes issues with
    both claiming modem devices.
  - debian/patches/02-dont-handle-stacktraces.patch: stop catching stacktraces
    and printing the information internally, so apport can catch and report
    the possible bugs.
  - debian/ofono.postinst: on configure, notify the user that a reboot is
    required (so ofono can get started by upstart). (LP: #600501)
  - debian/rules: pass --no-restart-on-upgrade so ofono isn't automatically
    restarted when upgrades.
  - Adding upstart config / Removing standard init script
  - Adding Apport support
  - Patch for recognizing special Huawei devices with weird serial
  - Override lintian to avoid script-in-etc-init.d... warnings.
  - Update debian/compat to 7
* debian/series: add our patches to debian/patches/series now that the package
  uses quilt.
* debian/patches/02-dont-handle-stacktraces.patch: refreshed.
* debian/ofono-dev.install, debian/ofono.install:
  - Install usr/sbin/dundee and ofono.pc to the proper packages.
