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.
