Import the gvinum work that have been done during and after Summer of Code 2007. The work have been under testing and fixing since then, and it is mature enough to be put into HEAD for further testing.
A lot have changed in this time, and here are the most important: - Gvinum now uses one single workerthread instead of one thread for each volume and each plex. The reason for this is that the previous scheme was very complex, and was the cause of many of the bugs discovered in gvinum. Instead, gvinum now uses one worker thread with an event queue, quite similar to what used in gmirror. - The rebuild/grow/initialize/parity check routines no longer runs in separate threads, but are run as regular I/O requests with special flags. This made it easier to support mounted growing and parity rebuild. - Support for growing striped and raid5-plexes, meaning that one can extend the volumes for these plex types in addition to the concat type. Also works while the volume is mounted. - Implementation of many of the missing commands from the old vinum: attach/detach, start (was partially implemented), stop (was partially implemented), concat, mirror, stripe, raid5 (shortcuts for creating volumes with one plex of these organizations). - The parity check and rebuild no longer goes between userland/kernel, meaning that the gvinum command will not stay and wait forever for the rebuild to finish. You can instead watch the status with the list command. - Many problems with gvinum have been reported since 5.x, and some has been hard to fix due to the complicated architecture. Hopefully, it should be more stable and better handle edge cases that previously made gvinum crash. - Failed drives no longer disappears entirely, but now leave behind a dummy drive that makes sure the original state is not forgotten in case the system is rebooted between drive failures/swaps. - Update manpage to reflect new commands and extend it with some examples.

- Import macros used in gmirror for printing gvinum debug messages and making the output more standardized. - Add a sysctl to set the verbosity of the debug messages. - While there, fixup typos and wording in the messages.

Rename the kthread_xxx (e.g. kthread_create()) calls to kproc_xxx as they actually make whole processes. Thos makes way for us to add REAL kthread_create() and friends that actually make theads. it turns out that most of these calls actually end up being moved back to the thread version when it's added. but we need to make this cosmetic change first.
I'd LOVE to do this rename in 7.0 so that we can eventually MFC the new kthread_xxx() calls.

Correct the check if a plex is accessible in case it is not up. This makes degraded RAID5 plexes actually work.

Correctly calculate what to do and how to retry a request to a plex when the previous one failed and there are more than one plex in the volume.
This could have led to a flood of error messages on the console and probably a deadlock in certain situations.

Although an object may already be known in the configuration, it's worker thread may have been destroyed (e.g. during orphaning).
Make sure that objects get back their worker threads when they get a new geom.

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.

When attaching a consumer from a volume to a plex, check if the volume already has a plex attached and adjust the access counts of the new consumer accordingly.
