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.

libubi is now used to format directly UBI volume.
Typing mkfs.ubifs /dev/ubi0_0 is now possible.
dtypes should be ok as they are taken from UBIFS code.

UBIFS may reserve some amount of flash space for the super-user,
ant this amount is stored in the superblock. Currently mkfs.ubifs
always puts 0 there. This patch adds -R option which may be used
to specify size of the reserved space.
