This is remotefilelog as of my recent patches for compatibility with
current tip of hg, minus support for old versions of Mercurial and
some FB-specific features like their treemanifest extension and
fetching linkrev data from a patched phabricator. The file extutil.py
moved from hgext3rd to remotefilelog.
This is not yet ready to be landed, consider it a preview for
now. Planned changes include:
- replace lz4 with zstd
- rename some capabilities, requirements and wireproto commands to mark them as experimental
- consolidate bits of shallowutil with related functions (eg readfile)
I'm certainly open to other (small) changes, but my rough mission is
to land this largely as-is so we can use it as a model of the
functionality we need going forward for lazy-fetching of file contents
from a server.
- no-check-commit because of a few foo_bar functions
