mtd-utils: flash_erase: Fix output of offsets
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:
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:

mtd-utils: nandwrite: Large page+oob support
Dynamic allocation of the oob buffer provides the necessary
support for removing the oob size check. Now, new unknown OOB
sizes can be handled correctly (for example, 8KB page + 448B
OOB).
Included common.h for the use of xmalloc.
Memory freeing should occur on "restoreoob" as well as on
"closeall."

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.

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.
