Fix problem with geom_label(4) not recognizing UFS labels on filesystems
extended using growfs(8). The problem here is that geom_label checks if
the filesystem size recorded in UFS superblock is equal to the provider
(i.e. device) size. This check cannot be removed due to backward
compatibility. On the other hand, in most cases growfs(8) cannot set
fs_size in the superblock to match the provider size, because, differently
from newfs(8), it cannot recompute cylinder group sizes.

To fix this problem, add another superblock field, fs_providersize, used
only for this purpose. The geom_label(4) will attach if either fs_size
(filesystem created with newfs(8)) or fs_providersize (filesystem expanded
using growfs(8)) matches the device size.

Improve growfs(8) in a few ways; unfortunately, it's somewhat hard to untangle
them and commit separately.

1. Rewrite the way growfs(8) finds the device and mount point. This makes
it possible to use e.g. "growfs /mnt"; it's also used to display more
helpful messages.

2. Be more user-friendly, using descriptive messages, like this:

OK to grow filesystem on /dev/md0, mounted on /mnt, from 9.8GB to 20GB? [Yes/No]"

3. Allow to specify the size (-s option) just like with mdconfig(8), i.e. with
postfixes ("mdconfig -s 10g").

4. Reload read-only filesystem after growing.

Remove block reallocation used to make room for the cylinder group
summary structure. From now on, when there is no room for it,
we simply allocate new one in a newly added cylinder group.

This patch removes a conditional in updcsloc(), reindents some code
there, and removes unused routines. I decided to do it this way instead
of disabling reallocation when the filesystem is live and leaving it
as it is otherwise, because this allows for removal of lots of complicated
and hard to test code. Also, conditionally disabling it would result
in a different layout in filesystems resized online and offline, which
would look somewhat weird.
