The fsck_ffs program had previously only been able to expand the size

Description

The fsck_ffs program had previously only been able to expand the size
of its lost+found directory by allocating direct block pointers. The
effect was that it was limited to about 19,000 files. One of Peter Holm's
tests produced a filesystem with about 23,000 lost files which meant
that fsck_ffs was unable to recover it. This update allows lost+found
to be expanded into a single indirect block which allows it to store
up to about 6,573,000 lost files.
