commit 90ecab35525ea3637a59763d75df6712ff91728a
Author: Michael Neumann <mneumann@ntecs.de>

Expand HAMMER filesystem step 1/2
Format the volume and increase other volumes' vol_count field.
The space of the new volume is not yet given to the filesystem (that's step 2).
Example:
newfs_hammer -L TEST /dev/da0
mount_hammer /dev/da0 /hammer
hammer expand /hammer /dev/da1
umount /hammer
mount_hammer /dev/da0:/dev/da1 /hammer
# the following fails (wrong number of volumes)
mount_hammer /dev/da0 /hammer
