rHGe2a1584e9e3f: remotefilelog: rip out lz4 support

Summary

Some methods are left teased out so it's easier to build a migration
extension from v1 packs to v2. I also anticipate those methods will be
of use if we get around to adding configurable compression engines
before we end up jettisoning packs.

I think it would make sense to register one-shot compress and
decompress methods on our compression engines in util.py, but
indygreg mentioned that might not be straightforward.

Get that non-standard LZ4 format outta here!

Yes, we should probably add a compression engine API for doing one-shot compression/decompression. I could use that in the SQLite extension. If you don't implement it, I may do it for you in the natural course of making that extension :)

I'm holding off formally accepting as a reviewer because the patch is marked WIP.

Please resubmit without that.

I'll need to take a pass over the final version of this code before committing. But I'm pretty sure the current state of this series is good enough or pretty close to being landable.
