Eelco Dolstra 0ab64729e9 Improve GitHub caching
In particular, when building a flake lock file, inputs like 'nixpkgs'
are now downloaded only once. Previously, it would fetch
https://api.github.com/repos/<owner>/<repo>/tarball/<ref> and then
later https://api.github.com/repos/<owner>/<repo>/tarball/<rev>, even
though they produce the same result.

Git and GitHub now also share a cache that maps revs to a store path
and other info.

Add date of last commit to SourceInfo
This is primarily useful for version string generation, where we need
a monotonically increasing number. The revcount is the preferred thing
to use, but isn't available for GitHub flakes (since it requires
fetching the entire history). The last commit timestamp OTOH can be
extracted from GitHub tarballs.

Eelco Dolstra 0cbda84f5b exportGit: Don't clone local repositories
This ensures that commands like 'nix flake info /my/nixpkgs' don't
copy a gigabyte of crap to ~/.cache/nix.

Fixes #60.

Eelco Dolstra 6a4c7fb975 Add path flakeref variant
Unlike file://<path>, this allows the path to be a dirty Git tree, so

  nix build /path/to/flake:attr

is a convenient way to test building a local flake.
