If the memory used to copy the link_make is "dirty" the string wont
be ended with NULL, throwing out multiple memory bugs.

7d3d30b1b3 UBIFS: Remove tnc_commit.c which is not used in the read-only version
I missed removing this file while implementing the UBIFS support. It's
not referenced at all, so let's remove it. Thanks to Artem Bityutskiy
for spotting.

6356daff70 UBIFS: fix recovery bug
UBIFS did not recovery in a situation in which it could
have. The relevant function assumed there could not be
more nodes in an eraseblock after a corrupted node, but
in fact the last (NAND) page written might contain anything.
The correct approach is to check for empty space (0xFF bytes)
from then on.

febd7e4174 UBIFS: add R/O compatibility
Now UBIFS is supported by u-boot. If we ever decide to change the
media format, then people will have to upgrade their u-boots to
mount new format images. However, very often it is possible to
preserve R/O forward-compatibility, even though the write
forward-compatibility is not preserved.

This patch introduces a new super-block field which stores the
R/O compatibility version.

faac4fd852 UBIFS: Missing offset relocation for compressor 'none'
On systems where U-Boot is linked to another address than it really lays
(e.g. backup image), calls via function pointers must be fixed with a
'+= gd->reloc_off'.
This was not done for none_compr in ubifs_compressors_init() what leads
to system crash on ubifsmount command.

9eefe2a2b3 UBIFS: Implement read-only UBIFS support in U-Boot
The U-Boot UBIFS implementation is largely a direct copy from the current
Linux version (2.6.29-rc6). As already done in the UBI version we have an
"abstraction layer" to redefine or remove some OS calls (e.g. mutex_lock()
...). This makes it possible to use the original Linux code with very
little changes. And by this we can better update to later Linux versions.

I removed some of the Linux features that are not used in the U-Boot
version (e.g. garbage-collection, write support).
