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.

Restrict binary dumping so that by default, binary garbage is not
printed directly to a terminal. Output redicted to files or piped to
other commands should not be affected (as judged by "isatty(ofd)").
A new flag "-a" or "--forcebinary" is included so that users can
override this behavior if necessary.

Added the "-c" or "--canonicalprint" flag (modelled off 'hexdump -C')
so that users can choose to print ASCII output next to the prettyprint
output. This is really an extension to the prettyprint option, so the two
options do not conflict if they are both included in the same execution.

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.
Tested with Samsung K9GAG08U0D

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.

Much to my regret I can't provide a URL because is not public. IGEP v2
board has a Onenand with two dice of 2048/64 spare combination but mtd
views 4096/64. The minimal write page is 4K (2K from first dice and 2K
from second dice).

The tool mkyaffs2image doesn't know the oob layout of a NAND flash, so it
puts the yaffs2 tags at the offset 0 of oob area, as a result, the image
generated by mkyaffs2image is different with the image dumped by nanddump.
Now adding a parameter "-r" for nandwrite to differentiate these images.
Write a image generated by mkyaffs2image:
$> nandwrite -a -o /dev/mtd3 yaffs2.bin
Write a image dumped by nanddump:
$> nandwrite -a -r /dev/mtd3 image.bin

struct ubi_attach_request now has additional field 'dev' that can contain path
to the MTD device node in the filesystem. Also there are two new functions that
are able to handle path to the MTD device node:
ubi_attach() - attach MTD device by number or by path
ubi_detach() - detach MTD device by path
ubi_attach() works like ubi_attach_mtd() when it is passed empty req->dev,
otherwise it looks up correct MTD device number based on the given device node
path.
