Currently users of mm.h need to include <linux/slab.h> to use the macros
malloc() and free() provided by mm.h. This fixes it.

set_error_fn() has become a useless complication after c1e7c3ae59
("bzip2/lzma/gzip: pre-boot malloc doesn't return NULL on failure") fixed
the use of error() in malloc(). Only decompress_unlzma.c had some use for
it and that was easy to change too.
This also gets rid of the static function pointer "error", which
should have been marked as __initdata.

Fix checkstack error:

byteCount, symToByte, and mtfSymbol cannot be declared static or allocated

These includes were added by 079effb6933f34b9b1b67b08bd4fd7fb672d16ef
("kmemtrace, kbuild: fix slab.h dependency problem in
lib/decompress_inflate.c") to fix the build when using kmemtrace. However
this is not necessary when used to create a compressed kernel, and
actually creates issues (brings a lot of things unavailable in the
decompression environment), so don't include it if STATIC is defined.

decompress_bunzip2 and decompress_unlzma have a nasty hack that subtracts
4 from the input length if being called in the pre-boot environment.
This is a nasty hack because it relies on the fact that flush = NULL only
when called from the pre-boot environment (i.e.
arch/x86/boot/compressed/misc.c). initramfs.c/do_mounts_rd.c pass in a
flush buffer (flush != NULL).
This hack prevents the decompressors from being used with flush = NULL by
other callers unless knowledge of the hack is propagated to them.
This patch removes the hack by making decompress (called only from the
pre-boot environment) a wrapper function that subtracts 4 from the input
length before calling the decompressor.

Impact: cleanup
lib/decompress_bunzip2.c depends on slab.h without including it:
CC lib/decompress_bunzip2.o
lib/decompress_bunzip2.c: In function ‘start_bunzip’:
lib/decompress_bunzip2.c:636: error: implicit declaration of function ‘kmalloc’
lib/decompress_bunzip2.c:636: warning: assignment makes pointer from integer without a cast
lib/decompress_bunzip2.c: In function ‘bunzip2’:
lib/decompress_bunzip2.c:682: warning: assignment makes pointer from integer without a cast
lib/decompress_bunzip2.c:693: warning: assignment makes pointer from integer without a cast
lib/decompress_bunzip2.c:726: error: implicit declaration of function ‘kfree’
make[1]: *** [lib/decompress_bunzip2.o] Error 1
make: *** [lib/] Error 2
It gets included implicitly currently - but this will not be the
case with upcoming kmemtrace changes.

Impact: Replaces inflate.c with a wrapper around zlib_inflate; new library code
This is the first part of the bzip2/lzma patch
The bzip patch is based on an idea by Christian Ludwig, includes support for
compressing the kernel with bzip2 or lzma rather than gzip. Both
compressors give smaller sizes than gzip. Lzma's decompresses faster
than bzip2.
It also supports ramdisks and initramfs' compressed using these two
compressors.
The functionality has been successfully used for a couple of years by
the udpcast project
This version applies to "tip" kernel 2.6.28
This part contains:
- changed inflate.c to accomodate rest of patch
- implementation of bzip2 compression (not used at this stage yet)
- implementation of lzma compression (not used at this stage yet)
- Makefile routines to support bzip2 and lzma kernel compression
