b83d5cd619 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.

fc5a15a34b 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.

8bc23a2edf 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().

d360d6d42f There's a chance that the VINUMDRIVE class tastes before the 
VINUM class, so let the VINUMDRIVE class parse the on-disk
configuration, too.

9795b96112 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>.

d754d951b9 Mark a plex as 'newborn' when it is created. This is used to indicate 
that new RAID5 plexes need to be initialized first.

7e172b8cb6 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.

7429d59ed6 Don't free a VINUMDRIVE softc when it's orphaned or spoiled. All 
allocated ressouces should be ultimately freed in gv_destroy_geom()
(when unloading the module and not earlier), but I need to look at this
more closely.
