remotefilelog: rip out lz4 support
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.

remotefilelog: bump pack file formats to version 2
Drop support for format 0 and 1 packs. Version 2 will be different in
that it'll use zlib compression instead of lz4, as the latter isn't
really suitable for core.
If I can make it work, I'll make compression engines pluggable, but
the logic for handling these files is spread out enough it's a little
tricky to get that right.
Test changes are only due to pack files being renamed. The contents of
the packs are the same.

remotefilelog: avoid hard-coding pack names in tests
I'm about to alter the pack format, which alters the content-addressed
name of the pack file. In order to reduce my own confusion I found it
helpful to use an ls | head pipeline since we always want to inspect
the newest pack.

remotefilelog: remove support for fetching packs
We've never used this at Google, and it's strictly an optimization
that indygreg and I are confident we can handle more elegantly
later. Let's rip it out to keep the surface area of the imported
remotefilelog small.
Some tests have changes because the tests for regular packs and
repacking were mixed with tests of fetching packs. I'm pretty sure
I've done the right thing here.
