When reading and writing OOB we specify the address as absolute
offset from the beginning of the MTD device. This offset is
basically an absolute page offset plus the OOB offset. And it does
not have to be aligned to the min. I/O unit size (NAND page size).
So fix the 'do_oob_op()' function and remove incorrect checking
that the offset is page-aligned. This check leads to the following
errors:
libmtd: error!: unaligned address 2, mtd0 page size is 2048
But obviously, the intent was to write to offset 2 of the OOB area
of the very first NAND page.
Instead of that incorrect check, we should check that the OOB offset
we write to is within the OOB size and the length is withing the OOB
size. This patch adds such check.

The integck tests re-mounts the file-system from time to time
and checks the integrity afterwords. And it re-mounts always
the same-way: unmount and then mount R/W back. However, it is
better to do it differently some times, e.g.:
* re-mount R/O then re-mount R/W
* unmount then mount R/W
* both of the above
* unmount, mount R/O, then re-mount R/W
* etc.
This will give better test coverage. This patch does exactly
that by improving the 'tests_remount()' function.

Commit a8801d8 (unify flash_erase and flash_eraseall) changed the
flash_erase interface in a backwards incompatible way. Before that
commit start position was given in bytes, and now it must be provided
in blocks.
While I agree the new interface is nicer, we shouldn't break the
interface. I have scripts that expect the old behaviour, and I'm
most likely not alone, so change the interface back to the old
way.

We must use "long long" and "unsigned long long" types when
implementing the functions "simple_strtoll()" and "simple_strtoull()",
respectively. This prevents casting/truncation errors on systems where
"long" is not the same size as "long long" (that is, on most systems).

Several ioctls are replaced with libmtd calls which should give us 64-bit
support for large devices. libmtd mostly provides drop-in replacements
for the functionality we need. However, when we require erasure of a
badly-written block, mtd_erase() only erases a single block, whereas
MEMERASE could erase a larger region. In nandwrite, we may have a "virtual
blocksize" of more than one (when blockalign > 1). Thus, I added a loop
for this case.
The mtd_oob_buf struct is no longer needed, nor is "erase_info_t".
Error messages for the new libmtd calls reflect the style found in
flash_erase.
Tested with nandsim and with NAND chips up to 4GB in size (I don't have
a device that truly requires 64-bit addressing yet).

For large block- and page-sizes, the multiplication of ebsize_aligned
and pagelen can overflow a 32-bit integer. This overflow can be
prevented by a simple change in order of operations (i.e., do division
first).
Since ebsize_aligned is always a multiple of mtd.min_io_size, this
produces no change in results.

Commit 07005d915d6a79dbdee14b0c4360df5058c3a98b made changes to the
buffer allocation in nandwrite and did not handle all affected code
areas properly. In particular, we were assigning:
oob.ptr = noecc ? oobreadbuf : oobbuf;
However, since oobreadbuf and oobbuf are declared dynamically, they
are NULL at this point. If they aren't properly assigned later, we
unwittingly are passing a NULL pointer as oob buffer.
This assignment line is best moved after the buffer allocations and
pointer assignment.
Effects of this problem can be seen when writing oob data with the "-o"
flag and without the "-n" flag:
$ ./nandwrite -o /dev/mtd0 img.bin

Begin utilizing libmtd for MTD operations: use mtd_get_dev_info() to return
a more detailed set of information about our MTD. Most importantly, libmtd
will yield a 64-bit "size" parameter. This is necessary to properly detect
devices larer than 4GB.
printf() arguments needed reformatted for the new mtd_dev_info data types.
In addition, the printf() was restructured to keep lines shorter.

Due to the presence of the "--block-align" flag, nandwrite uses a
blocksize throughout that, depeding on the execution parameters, may
not be the actual erasesize of the NAND flash. In order to clarify
this situation for the untrained viewer of nandwrite's code, we should
not change the value of "meminfo.erasesize" itself; rather, we can
utilize a separate, calculated "ebsize_aligned". Then, when a user
actually wants to refer to the physical erasesize, it's straightforward.

Comment on "blockalign" default value is incorrect; it only defaults
to a 1x multiplier of the actual block size. Perhaps this is a relic
of early NAND where all block sizes were 16KB?

Adds support for 64-bit offsets (i.e., devices larger than 4GB).
Utilizes the "unsigned long long" data type as the standard type
for 64-bit offsets throughout. Reformats a few printf statements
to avoid casting and to properly handle "long long."
Calls to ioctls are mostly replaced by libmtd interfaces (which should
choose the proper ioctls for us); however, a few remain and probably
should be handled with more robust interfaces, as some of these
ioctls are considered "legacy."

There were some signed/unsigned integer comparisons. Their types were
changed for safety. Also, "strtol" was improperly used for unsigned
data types.
Nanddump's pretty print options needed a slight reformat to prepare for
printing offsets that are more than 32 bits (8 hex characters) wide.
This prevents overlap of output and ensures that at least one space is
printed between hex and ascii printouts. Perhaps this could use some
better alignment in the future.
Other fixes:
* Corrected several simple spacing issues
* Changed indentation of some global variable declarations in
order to prepare for the next patch, which makes those
declarations longer
* Used macro for PRETTY_ROW_SIZE instead of constant 16
* Reformatted, edited a multi-line comment
* Removed some unnecessary casts

Need to use unsigned arithmetic and a 64-bit cast in order to
calculate and output the correct offset for eraseblocks at large
offsets. Signed integer arithmetic does not produce the correct
result "uint64_t" result, so for offsets over 2GB we get
messages like:
Erasing 512 Kibyte @ ffffffff83180000 -- 4308642136 % complete.
Note that this error was not affecting proper erasure; it just
produced incorrect status messages.
Also, we should not add an extra eraseblock for the final status
message; this gives misleading output when, for example, the
following statement is executed:
$ flash_erase /dev/mtd0 0 1
Erasing 512 Kibyte @ 80000 -- 100 % complete
We aren't erasing at offset 0x80000; it should display offset 0.

sizes can be handled correctly (for example, 8KB page + 448B

The buffers used for dumping page and OOB data needed dynamic
allocation to help eliminate burdens for updating (i.e., every
time there's a new OOB size we don't have to increase the sizes).
Also, there is no need to check flash chips for "standard sizes."
With recent changes to the printing codebase, we should be able to
handle arbitrary sizes with no problem.
More exit operations are now necessary on program failure, so
"goto closeall" is used more liberally.
Also, common.h is included for the use of xmalloc.

Since these functions take no parameters, declare them as such. The
subtle difference here is that gcc allows (without warning) people to
