[RFC] An rsync friendly gzip

[Martijn van Oosterhout <kleptog@cupid.suninternet.com>]

Hi,

I've heard about this idea for a while now and I've talked
to Andrew Tridgell about it and so finally I got around to
writing a very simple version to do some (simple) tests on it.

Full results are at:
http://cupid.suninternet.com/~kleptog/rgzip.html

Source code is at:
http://cupid.suninternet.com/~kleptog/rgzip.c

Summary:

1. Currently a bit slow
2. Currently increases compressed size by around 3%
3. For small changes in the source, can reduce download
   by over 95%.
