This did very little, and especially the part of relying on the outside
caller to pass in a Directory if the type is a directory required having
per-entry-type specific logic anyways.
It's cleaner to just inline it.

When a directory or file is open()'ed, we already put some data into
a lookup table, and subsequent operations then use the returned handle
id.
By also adding the span that's been created during these calls into the
lookup table, we can properly set the span parent for these requests,
nicely connecting the individual operations to the bigger picture.

Similar to how we already handle opening files, implement opendir/
releasedir, and keep a map of dir_handles. They point to the rx side of
a channel.
This greatly improves performance listing the root of the filesystem
when used inside tvix-store, as we don't need to re-request the listing
(and skip to the desired position) all the time.

This allows copying individual store paths from the local /nix/store
into tvix-store.
As we don't support getting this information from Nix yet, we currently
expect metadata to be provided externally:
Nix' `exportReferencesGraph` feature contains pretty much all data we
need for this. Expect a list of this information at a well-known key
(`closure`, similar to nixpkgs' `pkgs/build-support/binary-cache/
default.nix`).
We currently simply upload all store paths sequentially, without any
parallelism or awareness in how the reference graph looks like.
As long as the connected stores don't enforce this, this is fine, at
least for now.

`toJSON` transform a Nix structure into a JSON string.
For each context in that Nix structure, the JSON string must possess it.
Thus, it is necessary to take the union of all contexts and attach it to
the final structure.
Unfortunately, the return type of `into_json` is a serde's JSON object,
not a string. Therefore, it is not possible to reuse `NixString`
machinery.
Context tests are reinforced as Nix does not test those behaviors.
Fixes b/393.

Right now `builtins.hashFile` always reads the entire file into memory
before hashing, which is not ideal for large files. This replaces
`read_to_string` with `open_file` which allows calculating the hash of
the file without buffering it entirely into memory. Other callers can
continue to buffer into memory if they choose, but they still use the
`open_file` VM request and then call `read_to_string` or `read_to_end`
on the `std::io::Reader`.

intended to, because I'm too stupid to count. Fix that, and also update
a leftover _debug in a test name.

Moving out the handshake route out of tvix-daemon to nix-compat.
We're bumping the protocol to version 37. It does not change anything
for us. Version 37 introduced a change in the build result
serialization. We do not implement that for now.
Tested tvix-daemon against Nix via the integration test to make sure
we did not break anything in the process.
Taking advantage of this refactor to remove the unused anyhow
dependency in tvix-daemon.
