Update ffsinfo(8) to use new UFS2 support in the growfs(8) debugging functions. Largely consists of renaming fields and types to be aware of the UFS1/UFS2 distinction, relying on libufs(3) to open and sanity check the device/file/label accessed. Since libufs(3) now handles label/UFS interactions, remove -L argument. Note: when submitted, this patch had substantial style changes. I've attempted to remove the restyling from the patch to separate the functional and style changes. Submitted by: Lukas Ertl <l.ertl@univie.ac.at> PR: bin/53517

* ffsinfo(8) is a tool to dump all metadata of a file system. It helps to find

* an fsck(8), and compare the two ascii dumps easy with diff, and you see
|
|
* directly where the problem is. You can control how much detail you want to
|
|
* see with some command line arguments. You can also easy check the status
|
|
* of a file system, like is there is enough space for growing a file system,
|
|
* or how many active snapshots do we have. It provides much more detailed
|
|
* information then dumpfs. Snapshots, as they are very new, are not really
|

* supported. They are just mentioned currently, but it is planned to run
|
|
