By using the same error message string, we only need one copy of it
in memory at runtime.

The current fec code casts a pointer to an int which causes warnings on
64bit systems. So create a macro for the duplicate/complicated magic
computation, and add an unsigned long cast in it to fix the original
problem.

libcrc32.a was generated without external symbols: nm -g libcrc32.a shoed
nothing. This patch fixes it to make libcrc32.a build to be the same as
libmtd.a. Frankly, I do not know why this happened and why this patch fixes
the issue, sorry for my ignorance. But this works.

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.

Fixed several compiler warnings, mainly when compiling on 64-bit
architectures (where "size_t"-related types are not necessarily
32-bit).

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.

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.
