MFC r234846:

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.

MFC r235079:

Fix offset calculation to actually rewrite the _last_ block.

Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Approved by: re (implicit)

Revert the mechanical change from 'file system' to 'filesystem', committed
in r223429. As bde@ pointed out, it was mostly backwards.

Cosmetic fixes; mostly s/file system/filesystem/g and removing weird indent
from messages.

We now have multiple filesystems (UFS, ZFS, ...), so for tools that only
operate on one type of filesystem, mention this.
While here, capitalise the use of "UFS" in growfs.8 to match other uses of
the term in other man pages.
