mkfs.ubifs: add "-F" option for "free-space fixup"
This adds a superblock flag indicating that "free-space fixup" is needed, and
allows it to be set by the user via the "-F" command-line option. The first
time the filesystem is mounted, this flag will trigger a one-time re-mapping of
all LEBs containing free space. This fixes problems seen on some NAND flashes
when a non-UBIFS-aware flash programmer is used.
Artem: add a bit more help text, tweaked the patch a bit.
Thanks to Ben Gardiner <bengardiner@nanometrics.ca> for help.
