ubifsmount is not working and causes an access with
a pointer set to zero because the ubifs_fs_type
is not initialized correctly.

Prototype for gunzip/zunzip was only in lib_generic/gunzip.c and thus
repeated in every file using it. This patch moves the prototypes to
common.h and removes all prototypes distributed anywhere else.

There is more and more usage of printing 64bit values,
so enable this feature generally, and delete the
CONFIG_SYS_64BIT_VSPRINTF and CONFIG_SYS_64BIT_STRTOUL
defines.

Add #ifdefs where necessary to not perform relocation fixups.  This
allows boards/architectures which support relocation to trim a decent
chunk of code.

Note that this patch doesn't add #ifdefs to architecture-specific code
which does not support relocation.

Files in directories which are symlinked to were not dereferenced
correctly in last commit. E.g., with a symlink

   /boot/lnk -> /boot/real_dir

loading

   /boot/lnk/uImage

will fail. This patch fixes that by simply seeing to it that the target
base directory has a slash after it.

This patch adds support for resolving symlinks to directories as well as
relative symlinks. Symlinks are now always resolved during file lookup,
so the load stage no longer needs to special-case them.

__set_bit and __clear_bit are defined in ubifs.h as well as in
asm/include/bitops.h for some architectures. This patch moves
the generic implementation to include/linux/bitops.h and uses
that unless it's defined by the architecture.

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.

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.

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.

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.

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).
