MFC r260068, r260069, r260076

 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
