This patch series adds checkpoint compression functionality, while
running under Remus.

Tested under xen-4.2-unstable/pvops dom0 (x86_64) #ubuntu-10.04.

A simple benchmark: SpecJBB (Java Benchmark)
- 4 minute Remus run, with PV domU (2.6.32 xenolinux kernel), 1G memory and 2 
VCPUs
- Data sent without compression: ~70GB.
- Data sent with compression: ~8GB.

Changes since last version:
1. use posix_memalign only on linux platforms and switch to normal malloc for
   the rest. stubdom compiles successfully.
