e35497f13b 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.

9f2d8a3834 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.

8f061f61db After r232548, clang complains about the apparent '=-' operator (a
left-over from ancient C times, and a frequent typo) in growfs.c:

sbin/growfs/growfs.c:1550:8: error: use of unary operator that may be intended as compound assignment (-=) [-Werror]
        blkno =- 1;

Use 'blkno = -1' instead, to silence the error.

275e1cf79b 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.

e29560acd7 Unbreak the build on strong-aligned architectures (arm, ia64).
Casting from (char *) to (struct ufs1_dinode *) changes the
alignment requirement of the pointer and GCC does not know that
the pointer is adequately aligned (due to malloc(3)), and warns
about it. Cast to (void *) first to by-pass the check.

1ad5f80fac Revise r197763 which fixes filesystem corruption when extending
into un-zeroed storage.

The original patch was questioned by Kirk as it forces the filesystem
to do excessive work initialising inodes on first use, and was never
MFC'd.  This change mimics the newfs(8) approach of zeroing two
blocks of inodes for each new cylinder group.

08f353ebe3 When growing a UFS1 filesystem, we need to initialise all inodes in any new
cylinder groups that are created.  When the filesystem is first created,
newfs always initialises the first two blocks of inodes, and then in the
UFS1 case will also initialise the remaining inode blocks.  The changes in
growfs.c 1.23 broke the initialisation of all inodes, seemingly based on
this implementation detail in newfs(8).  The result was that instead of
initialising all inodes, we would actually end up initialising all but the
first two blocks of inodes.  If the filesystem was grown into empty
(all-zeros) space then the resulting filesystem was fine, however when
grown onto non-zeroed space the filesystem produced would appear to have
massive corruption on the first fsck after growing.
A test case for this problem can be found in the PR audit trail.

Fix this by once again initialising all inodes in the UFS1 case.

4bdcc9c7d7 The cylinder group tag cg_initediblk needs to match the number of inodes
actually initialized. In the growfs case for UFS2, no inodes were actually
being initialized and the number of inodes noted as initialized was the
number of inodes per group. This created a filesystem that was deemed
corrupted because the inodes thus added were full of garbage.

e7c4605481 3 important fixes for growfs:
1) ginode() is passed a cylinder group number and inode number.  The inode
number is relative to the cg.  Use this relative number rather than the
absolute inode number when searching the cg inode bitmap to see if the inode
is allocated.  Using the absolute number quickly runs the check off the end
of the array and causes invalid inodes to be referenced.

2) ginode() checks the absolute indoe number to make sure that it is greater
than ROOTINO.  However, the caller loops through all of the possible inode
numbers and directly passes in values that are < ROOTINO.  Instead of halting
the program with an error, just return NULL.

3) When allocating new cylinder groups, growfs was initializing all of the
inodes in the group regardless of this only being required for UFS1.  Not
doing this for UFS2 provides a significant performance increase.

These fixes allow growing a filesystem beyond a trivial amount and have
been tested to grow an 8GB filesystem to 1.9TB.  Much more testing would
be appreciated.
