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

8d3dfc2691 Add an -E option to mirror newfs's. The idea is that if you have a system
that was built before ffs grew support for TRIM, your filesystem will have
plenty of free blocks that the flash chip doesn't know are free, so it
can't take advantage of them for wear leveling.  Once you've upgraded your
kernel, you enable TRIM on the filesystem (tunefs -t enable), then run
fsck_ffs -E on it before mounting it.

I tested this patch by half-filling an mdconfig'ed filesystem image,
running fsck_ffs -E on it, then verifying that the contents were not
damaged by comparing them to a pristine copy using rsync's checksum
functionality.  There is no reliable way to test it on real hardware.

Many thanks to mckusick@, who provided the tricky parts of this patch and
reviewed the final version.

910b491e7e Update the actions previously attempted by the -D option to make them
robust. With these changes fsck is now able to detect and reliably
rebuild corrupted cylinder group maps. The -D option is no longer
necessary as it has been replaced by a prompt asking whether the
corrupted cylinder group should be rebuilt and doing so when requested.
These actions are only offered and taken when running fsck in manual
mode. Corrupted cylinder groups found during preen mode cause the fsck
to fail.

Add the -r option to free up excess unused inodes. Decreasing the
number of preallocated inodes reduces the running time of future
runs of fsck and frees up space that can allocated to files. The -r
option is ignored when running in preen mode.

14320f1e7f Add a new flag, '-C' which enables a special mode that is intended for
catastrophic recovery.  Currently, this mode only validates whether a
cylindergroup has good signature data, and prompts the user to decide
whether to clear it as a whole.

This mode is useful when there is data damage on a disk and you are
working on copy of the original disk, as fsck_ffs(8) tends to abnormally
exit in such case, as a last resort to recover data from the disk.

15fca934f6 Add support for the -F flag which determines whether a specified
filesystem needs foreground checking (usually at boot time) or
can defer to background checking (after the system is up and running).
See the manual page, fsck_ffs(8), for details on the -F and -B options.
These options are primarily intended for use by the fsck front end.

All output is directed to stdout so that the output is coherent
when redirected to a file or a pipe. Unify the code with the fsck
front end that allows either a device or a mount point to be
specified as the argument to be checked.

41cee58cd8 Added filesystem clean bit support. This only affects fsck during a
preen (-p), and in that case the filesystem is skipped if it is clean.
A new flag "-f" for 'force' has been added which basically gives back
the old behavior of checking all the filesystems all the time. This
very closely models the behavior of SunOS and Ultrix.
