Implement IMGDIFF operation in the client.

This operation is used to apply update on gzipped data with much smaller
diff data than bsdiff.

update_engine only calls ApplyImagePatch() with all the data, the actuall
implementation of the imgdiff format is in bootable/recovery/applypatch.

Test: mma & added unittest
Bug: 26628339
