Now that the other architecture-specific lib directories have been
moved out of the top-level directory there's not much reason to have the
'_generic' suffix on the common lib directory.

Commit dce3d79710 updated the zlib code to v0.95; this caused
conflicts when building for the "cradle" board, because the (pretty
generic) preprocessor variable "OFF" was used in multiple files.
Make sure to avoid further conflicts by #undef'ing it in zlib.c
before redefining it.

This patch optimizes the direct copy procedure.
Uses get_unaligned() but only in one place.
The copy loop just above this one can also use this
optimization, but I havn't done so as I have not tested if it
is a win there too.
On my MPC8321 this is about 17% faster on my JFFS2 root FS
than the original. No speed test has been performed in u-boot.

Removed stdio.h inclusion and moved trace macros to use printf avoiding to
write debug informations to standard error.

This patch adds watchdog reset call to allow its invokation during decompression
phase. This control was present on old zlib version and here it is
backported for those relevant routines. This patch is sent as a zlib separate
one beacuse it was not tested due to specific board lack.
zlib patches will be unified just in one when this will be validated through
tests.

This patch updates zlib to the latest stable version.
Only relevant zlib parts were ported to u-boot tree, as already did for the
current zlib (0.95). New zlib guarantees a faster inflate performances
other then others improvements as explained at www.zlib.net.
It also includes Alessandro Rubini's patches to allow 0 as destination pointer
and to call watchdog reset if required by architecture.

This reverts commit b201171f2b4d509f3ad510b214bee70ff902e3d6.

The commit caused problems for example when unpacking kernel images:

	   Uncompressing Kernel Image ... Error: inflate() returned -2
	   GUNZIP: uncompress, out-of-mem or overwrite error - must
	   RESET board to recover
