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.

As we have planned, make --nosquash-rino-perm option to be the
default. Deprecate both options at the same time and print a
warning if they are used. Later we can remove them
Also, bump mkfs.ubifs version number.

This addresses a couple of issues:
1) Code was only allowing these options if --root was NOT specified (the
opposite of the documented usage)
2) -q / -Q short options did not work
3) Spacing fixes in the error/warning strings

Hide zlib's crc32 in compr_zlib.c and mkfs.ubifs/compr.c.
jffs2reader.c and mkfs.jffs2.c don't actually use zlib, so punt the
include from the file.
mkfs.jffs2.c is implicitly using crc32 from zlib.h instead of the
local mtd_crc32, so fix the local usage. otherwise we get warnings
about undefined crc32 because the file was redirecting the prototype.

If max_leb_cnt (-c option) is set too low, set_lprops() will corrupt

When mkfs.ubifs is used with -r dir, it does not make the root UBIFS
inode uid/gid/permissions to be equivalent to dir's permissions, but
it makes root inode permissions to be equivalent to uid = git = 0
(root) and permissions = u+rwx go+rx.
Unfortunately, we cannot simply fix this bug, because mkfs.ubifs is
already used in production. Thus, we have introduce --squash-rino-perm
option which is the default and it preserves the old mkfs.ubifs
behavior. We also introduce --nosquash-rino-perm option which fixes
mkfs.ubifs behavior. If none of these options is used, we print a
warning. The plan is to make everyone use one of these options, then
make --nosquash-rino-perm to be the default and remove the warning,
and then eventually deprecate and remove both options.

Because of namespace collisions mkfs.ubifs uses crc32() implementation from
/lib/libz.so.1, which generates incompatible CRC and later on the kernel reports
many CRC errors.
Fix this by re-naming mtd-utils' crc32 function to mtd_crc32.

Source files for libmtd, crc32, and fec are scattered throughout the
tree. Move them to a central location so they can be built into a
common "libmtd.a" library used by all mtd-utils programs.
This patch only renames/deletes files and does not change the content.
Also modify the build system and source code so that libmtd.a can be built
from a "common" location (lib/). Statically link all utilities at the top
level with libmtd.a . Minor changes to mkfs.ubifs to allow using the common
crc32 implementation.

With the device table one can add /dev entries to the root file system
image. The device table file contains among others the fields minor,
start, increment and count. If there is an entry with minor=0 start=0
increment=32 and count=4 the mkfs.ubifs makes 128 device entries, with
minor numbers from 0 to 127. The correct version makes 4 entries with
minor number 0,32,64,96.
/dev/mtd c 640 0 0 90 0 0 2 7
This gives 14 devices /dev/mtdXX instead of 7 devices.
Due to this error mtd_debug info /dev/mtd3 delivers the information of
/dev/mtd1 instead of.
