lib/lzo: a 3 commit cluster
[*] lib/lzo: Rename lzo1x_decompress.c to lzo1x_decompress_safe.c
	Rename the source file to match the function name and thereby
	also make room for a possible future even slightly faster
	"non-safe" decompressor version.

[*] lib/lzo: Update LZO compression to current upstream version
	This commit updates the kernel LZO code to the current upsteam version
	which features a significant speed improvement - benchmarking the Calgary
	and Silesia test corpora typically shows a doubled performance in
	both compression and decompression on modern i386/x86_64/powerpc machines.
