To support the MEMWRITE ioctl, we will need a different sort of libmtd
interface for writing to flash. We will expand mtd_write to include more
functionality; for now, we just change the function definition and
description as we begin to add the actual functionality.

Kernel ABI header added a new ioctl, killed an old one, and exposed OOB
modes to user-space. Plus, it added a lot of documentation.
We have some trivial name changes for some MTD mode constants as well.

Instead of using two different output buffers for OOB data, let's just
use the same one for all output. This adds an extra memcpy, but it
simplifies some future work, so it's worth it.

The nandtest program monitors the corrected ecc stat to determine if an
ECC correction has taken place during the last write-read. If so, it
prints "ECC corrected".
The mtd subsytem will store the number of bits corrected in the corrected
ecc stat so update the nandtest output to print also the number of bits
corrected when performing the test.

We don't really use oobinfochanged anymore, since all the calls to the
MEMSETOOBSEL ioctls are gone. The remaining usage of it is superfluous
now, as the only case where it is changed is under the "noecc" condition
and the only case where it is tested is under the "!noecc" condition.
We also no longer need the "restoreoob" label and can instead simply
close everything done with the single remaining label, "closeall". Note
that `close(-1)' is legal, although useless.
Finally, we move `old_oobinfo' into the only block of code in which it's
used now.

The legacy -j (--jffs2) and -y (--yaffs) options haven't been
operational for a long time, since MEMSETOOBSEL was killed. I don't
think anybody will miss these options (correct me if I'm wrong). They
can be replaced by proper usage of MTD_OOB_AUTO modes.
The -f (--forcelegacy) option went hand in hand with -j and -y. Now that
-j and -y are gone, there's no use for -f. Kill it.

The `autoplace' option was meant to force an MTD_OOB_AUTO layout while
writing to flash. This option has not been properly supported for a very
long time, as the necessary ioctl, MEMSETOOBSEL, has been removed.
Apparently nobody uses this option. Kill it.
Other code depends on the availability of the `old_oobinfo' data, so we
move some code within a block that handles autoplacement if it's
*already* enabled. This, however, is inconsistent and should be cleaned
up shortly.
Note: this option may be re-implemented in the near future with the
addition of a new ioctl that allows on-the-fly chaning of MTD OOB modes.

This "fixes" a regression found in:
commit 266061ebd5d72391f0a0e831b018e8fc7fea68a1
mtdinfo: add regioninfo/eraseblock map display
On certain flash (NOR flash that have eraseblock region info),
`mtdinfo -a' tries to open the MTD node file, for use with the ioctl
MEMGETREGIONINFO; however, we didn't supply a device node path to
`mtdinfo -a', so it's using NULL, resulting in errors like:
mtdinfo: error!: couldn't open MTD dev: (null)
error 14 (Bad address)
For now, we can just skip dumping region_info with the `-a' flag. If we
find a better way to do this (e.g., export via sysfs, find device nodes
via automatic routines, etc.), then we can kill the workaround and this
FIXME should be removed.
The regression was first reported at:
http://lists.infradead.org/pipermail/linux-mtd/2011-July/037232.html
The result of recent changes is that we cannot get region_info for devices
via the `--all' option. We add a note in the help message warning that
mtdinfo may find more info when given a device patch, e.g., /dev/mtdX.

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.
