ubi-utils: bin2nand, nand2bin add support of different ecc layouts
Both tools were lacking support of alternate ECC layouts. Only our intitial
format was supported. With this change, it should be very easy to add more
layouts in addtion to the already supported ones, which are: IBM (our format),
and the MTD default layout. NAND OOB sizes of 512 and 2048 are currently
supported.
In contrast to the old version of bin2nand, the holes inbetween the ECC data
is now not filled with 0x00 anymore but instead 0xff (like deleted flash) is
used. This should not cause any difference. The testcase reflects the different
layouts too.

mkfs.jffs2: Set mkfs.jffs2 page size runtime instead of fixed
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.

ubi-utils: various fixes in unubi
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.

UBI-utils: add compare feature
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.
