The jffs2 compression framework provides a "model" argument when
compressing and decompressing, but the caller always passes in NULL
and the callees never use it. So punt this useless overhead.

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.

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.

Sometimes dumping bad blocks is useful, like when the data isn't actually

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.

This patch is based on Kevin Cernekee's patch posted to the MTD mailing
list. It adds 'mtd_read_oob()' and 'mtd_write_oob()' interfaces support.
The interfaces use MEMREADOOB64/MEMWRITEOOB64 MTD ioctls if possible, and
fall-back to MEMREADOOB/MEMWRITEOOB if the 64-bit versions are not supported.
The information about ioctls support is then cashed in 'offs64_ioctls'
libmtd flag.

This patch is base on Kevin Cernekee's patch posted to the MTD mailing
list. It adds MEMERASE64 support to the 'mtd_erase()' call. Now it
first tries to use MEMERASE64, and if that is not supported, falls
back to the old MEMERASE ioctl.
This patch also introduces an 'offs64_ioctl' flag to the libmtd
descriptor. However, we cannot initialize it in 'libmtd_open()',
because we need an MTD device node, which we do not have in
'libmtd_open()'. Thus, we firs mark this flag as "uninitialized",
and at the first invocation of 'mtd_erase()' we initialize it.
This also means that we have to pass the limbtd descriptor to
'mtd_erase()', to save the flag value. This, in turn, requires
tweaking 'mtd_erase()' users.
This is not very nice, but good enough so far.

Restrict binary dumping so that by default, binary garbage is not

Adapted code from the linux kernel hex_dump_to_buffer() (lib/hexdump.c)
to provide a more robust hexdump for the pretty option. Now, nanddump
can print out any size of OOB (or page for that matter...) without
having to worry about non-multiples of 16.
This also provides ability to dump ASCII format next to the hex output
once additional command-line flags are added.

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
