Import mountall-2.36.3 for precise.

The upstream lp:ubuntu/precise/mountall repository is stale and does not have a
branch or tag for the mountall-2.36.3 release that is currently published in
precise-updates.

NB: https://bugs.launchpad.net/ubuntu/+source/mountall/+bug/1103319

This bug report was closed as invalid because Ubuntu policy does not
technically require a source code control for system updates.
Import and squash the old dajhorn/mountall repository.
Add debian/source/format file.

And set "3.0 (quilt)" so that the patch series is automatically applied by the
Launchpad builder.

This requires the deletion of `.bzr-builddeb`, which is in the upstream
Launchpad repository but not in the official distro tarball. Otherwise:

dpkg-source: info: local changes detected, the modified files are:
 mountall/.bzr-builddeb/default.conf
dpkg-source: error: aborting due to unexpected upstream changes
