FreeNAS Code

make autosnap work with filesystem/zvol anme instead of mp_path

remove MountPoint from Replication, supposedly allow replication of zvols

remove MountPoint from Task, make it work with Zvol

Remove pidfile right before running autorepl.

Allow only one instance of this script be run at one time.

Rework r8033 so the control can happen at one single point.

Fixes ticket 459 and various confusing customer questions (we can always enable verbose debug mode later).

Properly set arg0.

Execute autorepl.py instead of calling them in parallel.

Consistently use timedelta instead of just replacing components.

This fixes #492.
