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

Tested under xen-4.2-unstable.

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. A revised compression stream format 
2. Changed the xc_remus_* interface to a generic xc_compression_* format
3. Fixed issues like unaligned access, missing bounds check, etc
4. General code cleanups.
