Message:

hr: auto assembly, refactor

Added automatic assembly (with hrctl -A). All disks or their partitions
are scanned for HelenRAID metadata and assembly is attempted.

Main volume list is now locked with RW lock. The volume list
manipulation functions are moved into util.c.

hr_{create,destroy}_vol_struct() are implemented for better reusability
and modularity.

Volume destroy/stop (hrctl -D) now returns EBUSY if someone has still
the volume open()-ed.
