Another posting of this series as I've added a few patches which fix a
problem with shallow block copy.

Patches 1-5 of the original series were pushed.

Patches 1-3 of this series were originally posted and reviewed
separately but were not pushed yet due to the ongoing freeze. They are
included as they make the snapshots actually usable.

Patches 4-9 are new and fix a problem in block copy. The changes
necessary would conflict with the snapshot code so this version rebases
everything and includes them here.

Patches 10-12 fix a snapshot locking regression as outlined in the
previous posting.

The rest is from the original external snapshot blockdevization series
with feedback applied.
