blockcheck() since we try to stat() the UID. This means that we fail to
reload the mount if we have indeed cleaned the read-only root file system.
To avoid this, rerun blockcheck() if the real name is different to the
original device name, once we have opened the device with opendev(3).

gets rid of #include <sys/dkio.h> in sys/ioctl.h and adds #include
<sys/dkio.h> to the places that actually want and use the disk
ioctls.
this became an issue when krw@'s X build failed when he was testing
a change to dkio.h.

instead, .It is required. Thus, move .Pp and text before the .Bl,
and remove the .Pp altogether where it is not needed.

feedback and ok jmc@, and sobrado@ also supports the direction.

different locations than before. Actually, the disklabel does not
contain enough info to completely reconstruct the locations of all
alternate sb's. So use a hardcoded list of all possible 1st alternate
sb locations, but don't forget to verify against the label.

free room in struct partition by packing fragment size and
fragments/block more tighlty and use the resulting space to make
offset and size 48 bits. For the disk part we use spare fields in
struct disklabel. Kernel converts in-mem copy of the on-disk
label if needed, disklabel(8) writes new version.
We are careful to only change fields not used by bootloaders.

The 'new' fsck would round this value up to a fragment boundary, and end
up trying to access memory beyond allocated space. From mickey@, okay

locations based on the disklabel.
- unit bug: disklabel size is in sectors, but superblock
fs size is in fragments.
- The disklabel contains the maximum superblock size, not the actual
as used by newfs.
- problem is that mkfs reduces track/sector and secors/track to
make the cylindergroup fit in a fs block. In this case the values
in the disklabel do not predict what's in the superblock.
This fixes all these problems. It correctly predicts the location
of all superblocks on all my filesystems I have online (sized between
100MB and 1000GB). Also tested with filesystems with different
block and fragment sizes.
Written this with a goto to make the diff easier to read.

fixes to most importamt problem (^C on the "MARK FILESYSTEM CLEAN?"

superblock might lead to crashes or other mishap. Now my fuzzed fs
images no longer crash fsck_ffs. ok mickey@ pedro@ millert@

Solves a case were fsck_ffs was causing a segv. If it didn't do that
it would have mangled the filesystem later, very probably.
