We have removed the -m option, but did not remove args.mtdn which represents
the -m parameters. Kill args.mtdn as well.

Some compilers will complain about use of strlen() within a static array

The ubi-utils/src/ subdir is tossed as it just complicates things for no
real gain. The dictionary.h header is relocated to the ubi-utils/include/
since other headers in there need it.
The top level clean is replaced with a `find -delete` on objects, so it
might prune more than necessary, but many projects now do this sort of
thing and no one complained there.
A "mkdep" helper generates the actual rule, and the variables are used
with "foreach" to expand these automatically.
The tests subdir is updated only to reflect the ubi-utils source move.
Otherwise, it is left untouched as making that non-recursive isn't really
worth the effort.
While we're gutting things, also through in kbuild style output while
building to make things more legible.

To work as a proper inverse to nandwrite, nanddump must not dump OOB data by
default. This patch prints a warning regarding the future change. We also
suggest using the new flag, `--oob', for transitioning to the next release
with new default behavior.
Note that we are changing `-o' to mean `--oob' in the next release,
similar to `nandwrite -o'. This is a break from previous behavior.

We have too many separate bad block handling methods:
--omitbad
--noskipbad
--skipbad
On top of these, we have the default option: that bad blocks are
replaced with 0xFF.
These options will be unified under --bb=METHOD. The end goal will be
something like:
----------------------------------------------------------------------------------------------
Old option New option Comment
----------------------------------------------------------------------------------------------
<default> --bb=padbad dump flash data, substituting 0xFF for any bad blocks
--noskipbad --bb=dumpbad dump flash data, including any bad blocks
--skipbad --bb=skipbad dump good data, completely skipping any bad blocks (new default)
--omitbad N/A very similar to `skipbad' (DEPRECTATED)
The BB options are all mutually exclusive, so we check that we do not
have more than one BB option explicitly enabled on the command line by
tracking whether or not a BB method has been set by the user.

This brings the mtdinfo utility in line with the functionality

(if the user has requested it). The eraseblock map also shows

This patch first of all, re-names 'mtd_islocked()' into 'mtd_is_locked()' since
this seems to be the name Mike wanted, and it looks a bit nicer.
This patch also makes 'mtd_is_locked()' print an error message if it fails. I'm
not sure if it is good idea for a library to do so, but all functions do this,
so it certainly _not_ a good idea to be inconsistent.
However, for the special case, when the the "is locked" ioctl is not supported
or is not valid for this device, we do not print an error message and return
ENOTSUPP error code.
Thus, the user can distinguish between real errors and non-fatal "not
supported" cases.

This basically reverts commit 43feb39f35a9ee0ed3 which changed the full
length calculation to be one less than one sector. I don't understand
the logic in the commit message where it states that the length should
be one sector smaller as this results in misbehavior at runtime.
For example, with a mtd device with total size 0x400000 and erase block
size of 0x20000 (which gives us a total of 32 sectors), this new logic
results in:
mtdLockInfo.start = 0;
mtdLockInfo.length = 0x3e0000; /* (32 - 1) * 0x20000 */
Calling MEMLOCK/MEMUNLOCK on the device with this range leaves the last
sector unchanged which is certainly not what we want. So drop this -1
part of the calculation.
To look at it another way, if we only attempt to lock one sector, this
calculation would end up with the .length set to 0. Calling MEMLOCK
with a length of 0 does not lock the sector as this simple code shows:
int main(int argc, char *argv[]) {
erase_info_t e0 = { 0, 0 }, e1 = { 0, 0x20000 };
int fd = open(argv[1], O_RDONLY);
ioctl(fd, MEMUNLOCK, &e1);
printf("%i\n", ioctl(fd, MEMISLOCKED, &e1));
ioctl(fd, MEMLOCK, &e0);
printf("%i\n", ioctl(fd, MEMISLOCKED, &e1));
}
MEMISLOCKED returns 0 both times. If we change the argument to MEMLOCK
to e1, then MEMISLOCKED returns 1.

The flash_lock util has a bit of extra argument checking, and it supports
a magic value of "-1" to mean "all blocks".
The flash_unlock util supports automatic 2nd/3rd arguments to unlock the
whole flash. It also supports multiple bases (not just hex) for selecting
the range of the device to unlock.
So tweak both utilities so that they have equivalent functionality again
by adding the missing features to each.

This patch adds a new option "--skipbad" to nanddump. It is subtly
different than "--omitbad". The following description was included in
the help message to attempt to clarify the differences.
Notes on --omitbad and --skipbad:
With either option, we stop dumping data when we encounter a bad block
and resume dumping at the next good block. However, with --omitbad, we
count the bad block as part of the total dump length, whereas with
--skipbad, the bad block is 'skipped,' that is, not counted toward the
total dump length.
