Some initial work is done, all testcases pass now. However a lot of the patch format is still unknown / not working, so do not expect anything other than the apitest to work yet. The next thing to do now, is to gather input, output and patch files, and analyze how the compression and patching works on bigger / more complex files. CORE-15417
