Place hostnames and similar information fully under the prison system. The system hostname is now stored in prison0, and the global variable "hostname" has been removed, as has the hostname_mtx mutex. Jails may have their own host information, or they may inherit it from the parent/system. The proper way to read the hostname is via getcredhostname(), which will copy either the hostname associated with the passed cred, or the system hostname if you pass NULL. The system hostname can still be accessed directly (and without locking) at prison0.pr_host, but that should be avoided where possible.
The "similar information" referred to is domainname, hostid, and hostuuid, which have also become prison parameters and had their associated global variables removed.

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.

- Make gvinum header on-disk structure consistent on all platforms by storing the gvinum header in fields of fixed size and in a big endian byte order rather than the size and byte order of the actual platform.
Note that the change is backwards compatible with the old gvinum configuration format, but will save the configuration in the new format when the 'saveconfig' command is executed.

Commit step 1 of the vimage project, (network stack) virtualization work done by Marko Zec (zec@).
This is the first in a series of commits over the course of the next few weeks.
Mark all uses of global variables to be virtualized with a V_ prefix. Use macros to map them back to their global names for now, so this is a NOP change only.
We hope to have caught at least 85-90% of what is needed so we do not invalidate a lot of outstanding patches again.

Introduce a new lock, hostname_mtx, and use it to synchronize access to global hostname and domainname variables. Where necessary, copy to or from a stack-local buffer before performing copyin() or copyout(). A few uses, such as in cd9660 and daemon_saver, remain under-synchronized and will require further updates.
Correct a bug in which a failed copyin() of domainname would leave domainname potentially corrupted.

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.

o The only indication of error condition is NULL value returned by the function;
o value pointed to by error argument is undefined in the case when operation completes successfully.

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.

Shuffle around the order in which the components are compiled.
This way, the VINUMDRIVE class is loaded before the VINUM class, but since geom does the tasting for newly arrived classes last-in-first-out, the VINUM class tastes first.
This removes the need to call gv_parse_config() in the drive taste path.

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.

Fix a stupid bug in the drive taste function: when checking if a drive is known to the configuration check also if it already has a geom. Without this check several needless geoms are created and valid configuration data was overwritten.
This change obsoletes the need for a separate geom to taste an offered provider and the consumer doesn't need to be opened with the exclusive bit set.

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).
Ideas borrowed from pjd@, quite a bit of testing by Matthias Schuendehuette <msch@snafu.de>.
