PM / Hibernate: Compress hibernation image with LZO
Compress hibernation image with LZO in order to save on I/O and

[rjw: Added hibernate=nocompress command line option instead of just
nocompress which would be confusing, fixed a couple of compiler
warnings, fixed kerneldoc comments, minor cleanups.]
