de257b1b7a 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.

7f74b7e086 Finally bring in what was produced during Google SoC 2005:
Add functions to rename objects and to move a subdisk from one drive
to another.

e3eb852545 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.

ee457df6ea 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.

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>.

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.
