Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs.
The SYSCTL_NODE macro defines a list that stores all child-elements of that node. If there's no SYSCTL_DECL macro anywhere else, there's no reason why it shouldn't be static.

- Don't return EAGAIN from gv_unload(). It was used to work around the deadlock fixed in r207671. - Wait for worker process to exit at class unload. The worker process was not guaranteed to exit before the linker unloaded the module. - Use 0 as the worker process exit status instead of ENXIO and style the NOTREACHED comment.

- Fix the issue with read access count modification on RAID-5 plexes properly. If the access counts were not increased and decreased in equal numbers by gvinum consumers, the read access count would be inconsistent with the write access count. Instead, modify the read access count with the write access count directly to prevent any inconsistencies.

- Split up the BIO queue into a queue for new and one for completed requests. This is necessary for two reasons: 1) In order to avoid collisions with the use of a BIOs flags set by a consumer or a provider 2) Because GV_BIO_DONE was used to mark a BIO as done, not enough flags was available, so the consumer flags of a BIO had to be misused in order to support enough flags. The new queue makes it possible to recycle the GV_BIO_DONE flag into GV_BIO_GROW. As a consequence, gvinum will now work with any other GEOM class under it or on top of it.
- Use bio_pflags for storing internal flags on downgoing BIOs, as the requests appear to come from a consumer of a gvinum volume. Use bio_cflags only for cloned BIOs. - Move gv_post_bio to be used internally for maintenance requests. - Remove some cases where flags where set without need.

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.

Since we want a vinum geom created anytime the module loads, move the geom creation to a seperate init function and ignore the tasting.
The config is now parsed only in the vinumdrive geom, which hopefully fixes the problem, that the drive class tasted before the vinum class had a chance, for good.
Also restore the behaviour that the module can be loaded at boot time and on a running system.

Fix a stupid logic bug introduced in geom_vinum_drive.c rev 1.18:
When a drive is newly created, it's state is initially set to 'down', so it won't allow saving the config to it (thus it will never know of itself being created). Work around this by adding a new flag, that's also checked when saving the config to a drive.

Remove test for zero sectorsize when tasting. This check doesn't seem to be necessary anymore, and it prevents tasting a valid drive when booting with geom_vinum already loaded, since SCSI disks set their sectorsize not until first opening them.

Use a temporary geom when tasting vinumdrives and lock the 'real' vinumdrive geom with an exclusive bit. This should fix the problem when underlying partitions overlap (i.e. the 'a' partition is at the same offset as the 'c' partition).

Currently, if the drives specified for volume creation are not active GEOM providers, it will result in a kernel panic.
If the GEOM provider or disk goes away before the volume configuration data gets written to the disk, it will result in another kernel panic.
o Make sure that the drives specified for volume creation are active GEOM providers.
o When writing out volume configuration data to associated drives, make sure that the GEOM provider is active, otherwise continue to the next drive in the volume.
