333d028407 fsck_ffs: Don't overrun mount device buffer
Maybe this case is impossible.  Either way, when attempting to "/dev/"-prefix a
non-global device name, check that we do not overrun the f_mntfromname buffer.

In this case, truncating (with strlcpy or similar) would not be useful, since
the f_mntfromname result of getmntpt() is passed directly to open(2) later.

0f8c0b0ae4 fsck_ffs: Adopt some type safety for the journalling checks.
fs_ncg is of type uint32, and we were indexing it with an int.
Fixed this using an unsigned type and adopt some other unsigned
indexes to remind us when we are dealing with unsigned numbers.

7703a6ff27 Add the -R option to allow fsck_ffs to restart itself when too many critical
errors have been detected in a particular run.

Clean up the global state variables so that a restart can happen correctly.

Separate the global variables in fsck_ffs and fsdb to their own file.  This
fixes header sharing with fscd.

Correctly initialize, static-ize, and remove global variables as needed in
dir.c.  This fixes a problem with lost+found directories that was causing
a segfault.

Correctly initialize, static-ize, and remove global variables as needed in
suj.c.

Initialize the suj globals before allocating the disk object, not after.
Also ensure that 'preen' mode doesn't conflict with 'restart' mode

776816d32b Speed up fsck by caching the cylinder group maps in pass1 so
that they do not need to be read again in pass5. As this nearly
doubles the memory requirement for fsck, the cache is thrown away
if other memory needs in fsck would otherwise fail. Thus, the
memory footprint of fsck remains unchanged in memory constrained
environments.

This work was inspired by a paper presented at Usenix's FAST '13:
www.usenix.org/conference/fast13/ffsck-fast-file-system-checker

Details of this implementation appears in the April 2013 of ;login:
www.usenix.org/publications/login/april-2013-volume-38-number-2.

2db62a6b1f - blk_equals() is too strict. If the journal entry defines more frags
than we're claiming it should still be considered an exact match.  This
   would previously leak frags that had been extended.
 - If there is a sequence number problem in the journal print the sequence
   numbers we've seen so far for debugging.
 - Clean up the block mask related debuging printfs.  Some are redundant.
