Since control device is not supported by UBI in mainline kernels,
we should not panic if it is absent.

Since there is often confusion what "eb" is - physical or logical
eraseblock. Fix libubi and change "eb" to "leb".

Add an 'ubiupdate' utility which is basically a changed and cleaned-up
version of ubiupdatevol. It is also consistent with other ubi tools.
ubiupdatevol should go away, because it has features which should not
be present in tools for end users. If one needs debugging capabilities,
he should create a separate program.
So, I do not delete ubiupdatevol, but it will be moved somwthere later.

This patch fixes a libubi bug and does some random minor cleanups.

Add new handy UBI utility which prints various type of UBI information.
This commit also includes a lot of fixes and cleanups in libubi, and
other utilities. It was quite complex to separate this all out and
I figured that nobody anyway would really need this, and decided to
save my time for more useful things.

This patch reads the default PAGE_SIZE from sysconf(), i.e. the system
mkfs.jffs2 is running on, instead of just setting it to 4096 (which of
course is valid for most systems but not all).
This is useful if mkfs.jffs2 is running on the target system, e.g. to
create a backup image during firmware upgrade, so that the page size does
not have to be set explicitly using a command line parameter.
The --pagesize option is supported just as before.
If the user has not set the page size explicitly with --pagesize, and
the system page size is anything other than 4096, warn the user that
an unusual page size is being used, since this behavior is different
from before.

Fixed a problem when ECC was checked. The correction was not properly
done by subpage. Added more output for the moment to be able to figure
out more potential problems.
Added testcase: bin2nand2bin.sh and biterror inject program inject_biterror.pl
Interface
o ECC correction disabled by default. Switch to turn it
explicitly on. The user must specify what he wants to be done.

The extraction of data from blocks used for dynamic volumes was
totally broken. The data size was calculated wrong. This fix is not
perfect, the alignment is still ignored.
The parameter "header-size" is very misleading. It does not reflect
the vid hdr offset properly. I assume therefor that it only works for
the layout I am using where the vid hdr is at the _end_ of the 1st
NAND page (2048).
I added the generation of a textfile with information about the blocks
which are going into the internal graph representation.
Instead of a graph I think that a simple array will simplify the code
very much. The array must than be sorted properly to cope with older
and newer block-copies but that should not be a problem.
discussed the tool with my coleage Andreas Arnez and we found that it
might be a good idea to replace it even with a perl program for the
same purpose since that would offer the flexibility to change it on
the fly when needed. The tool is mainly used for crash analysis so it
could be an advantage to change it without needing a C-compiler.

Drake Dawsett had done some changes to our unubi which where not yet
published. I hereby send his latest code and integrated the parameter
handling which was changed in our version. When reviewing this very
huge patch we need to ensure that possible changes of others are not
reversed.

When bad blocks occur more debug information is needed.
To identify the bad blocks the blocksize is required.
The split block mode was added to generate files per
block. In split mode the bad block markers are analyzed
and a summary is printed at the end.

Just silly hacks. Also remove udevsettle() invocation from UBI
library. If it must be called, it is not library's business
anyway. Wa added it to make scripts which use ubimkvol utility
run, so it is the only caller that really needs this. So
just move the cruft to the utility.

Send one packet from each eraseblock in turn, rather than all packets
for one eraseblock together. This means that bursts of loss are evenly
spread between blocks. It also makes the client side a bit more complex
if you can't assume that there's anywhere except the flash to store its
intermediate data.
