code duplication.

Make it possible to rebuild degraded RAID5 plexes. Note that it is
...
currently not possible to do this while the volume is mounted.

Re-vamp how I/O is handled in volumes and plexes.
...
Analogous to the drive level, give each volume and plex a worker thread
that picks up and processes incoming and completed BIOs.
This should fix the data corruption issues that have come up a few
weeks ago and improve performance, especially of RAID5 plexes.
The volume level needs a little work, though.

Compare the addresses of two RAID5 work packets directly instead
...
of the addresses of their related bios when locking one out, since
they could share a bio and this could lead to parity corruption.

Add a function to clean up RAID5 packets and use it when I/O has
...
finished or when building the complete packet fails.
