Library functions never reset errno to zero, so if you want
to use its value to check for errors then you must set it to zero
before calling the library function (in this case readdir).

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.

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.

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.

This is a new feature for pfiflash, called "--compare". It allows the user
to simulate a pfiflash session without actually changing the flash
content. If the flash content is equal to the data in the pfif file,
pfiflash returns zero. A positive value is returned when the flash
content differs from the pfi file, which indicates that an update is
necessary. This feature is useful when a controller mounts an NFS share
during boot and has to determine if a pfi file stored on this share
contains a code update. Modified PDD values are also registered by the
compare feature.

Ubimirror compares volumes before they are mirrored, but discards the
result of the comparison and alway copies volumes.
I've tested this code with equal and unequal volumes and it seems to work
fine now.

The tools had a mixture of different version numbers. This is changed now.
The internal change to move to remove glibc dependencies should be reflected
by an increase of the version number, so that we can react if trouble is
