902378dc87 fritz-tools: fritz_tffs_nand: get rid of struct tffs_sectors
This doesn't help and "[0]" gets in the way of bounds checks.

12564c5b86 fritz-tools: fix returning wrong values due to strncmp usage
When having two keys that start with the same characters and the second
key just has one character more nand_tffs_read and tffs_read return the
wrong value for the longer key. This is due to the usage of strncmp in
combination with the length of the shorter key which is usually first in
the list before the longer key and when strncmp matches, the search is
stopped. The problem only occurs when the length of the two keys is
different, not if just the last character is different. The fix is to
use strcmp and as such it will only return the value if the key (name)
and the key to look for (namefilter) have the same value and length. A
sample case returning wrong values is when keys macwlan and macwlan2 are
defined and querying macwlan2 returns the value for macwlan.

AVM devices based on Qualcomm IPQ40xx do not store sector health
information in the OOB area. Make this check optional to support this
platform.

7e12863252 fritz_tffs_read: get tffs size from input file
Use the size of the input file as maximum tffs size instead of a fixed
value. The tffs on a AVM Fritz 300E can be up to 512KByte for example.

Fixes a read error for the AVM Fritz 3370 where the tffs partition size
is 64Kbyte and smaller than the former default value of 256KByte.

8b3fa168b4 firmware: rework fritz-tools package
Split the fritz-tools into subpackages. fritz_tffs_read is usefull for
all Fritz boards where fritz-cal_extract is only required for the
Fritz 4040 at the moment.

Rename the tffs related binary to the more catchy name fritz_tffs and
move the whole package to utilities since the package doesn't really
provide a firmware file.

Make the fritz-tools available for all targets and build them shared.
The tffs is used by avm on lantiq and ar71xx as well.
