The 'check_run_no' field does not have to be 64-bit, it can be
32-bit instead and we can save 4 bytes per object. Actually, it
could also be 16-bit, and we could make link_count 16-bit as well,
but that would need a bit more work.

We do not have to store boolean flags in 'int' variables which
consume 4 bytes each, we can store those in bit-fields instead.

Turn "int checked" flag into 'char' flag to lessen memory
consumption a bit. Indeed, the test allocates a lot of these
data objects, so the size decrease from 36 to 32 bytes on
32-bit platforms is good to have.

The 'link_new()' function has only one user, and the user checks
that the third 'file' argument is non NULL, so remove this check
from 'link_new()'. Let's be consistent and assume the 3rd argument
is never NULL, just like the first and the second ones.
This is just a minor improvement.

Instead of using named union 'entry' in 'struct dir_entry_info'

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.

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
Writing data to block 0 at offset 0x0
ioctl(MEMWRITEOOB): Bad address
