6c39d46363 Give each plex a separate queue where held back bios are put on.
This lowers the CPU usage of the worker thread and prevents a
possible live lock on non-SMP machines.

MFC candidate.

c3aadfb9d6 Make it possible to rebuild degraded RAID5 plexes. Note that it is
currently not possible to do this while the volume is mounted.

67e3ab6ee5 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.

fce2deb197 Rename gv_kill_thread() to gv_kill_plex_thread(), since there are more
threads to come.

92f49a969d If we kill the worklist thread of a RAID5 plex we can destroy
the worklist mutex at the same time, so move the mtx_destroy() call
to gv_kill_thread().

3a1e11b485 Add a function to clean up RAID5 packets and use it when I/O has
finished or when building the complete packet fails.
