Remove a race condition which appears when uploadHashLayer is called
with the same key from multiple threads simultaneously. This can
easily happen when the same image path is requested by multiple
clients at the same time. When it does, a 500 status is returned and
the following error message is logged:
{
"context": {
"filePath": "github.com/google/nixery/builder/builder.go",
"lineNumber": 440,
"functionName": "github.com/google/nixery/builder.uploadHashLayer"
},
"error": "rename /var/lib/nixery/staging/<hash> /var/lib/nixery/layers/<hash>: no such file or directory",
"eventTime": "...",
"layer": "<hash>",
"message": "failed to move layer from staging",
...
}
To solve this issue, introduce a mutex keyed on the uploaded hash and
move all layer caching into uploadHashLayer. This could additionally
provide a small performance benefit when an already built image is
requested and NIXERY_PKGS_PATH is set, since symlink layers and config
layers are now also cached.

This is the New Thing that is intended to replace the find-owners
and owners plugins.
In particular:
* It inserts a submit requirement rather than providing a Prolog
predicate.
* The default OWNERS file formats are suspiciously Googley.
* It provides a neat UI for finding OWNERS and tracking approval
state on a per-file basis.
When we fully migrate to using the code-owners plugin, a few
things will need to land, which I will likely do "offline"
directly to the Gerrit backing Git repos:
* Add the corresponding Gerrit config
* Replace OWNERS files depot-wide
* Add OWNERS files to the refs/meta/config branch
* Introduce the Owners-Override label, settable by depot-interventions
The enclosed patch adds two extra pieces of functionality that
we need in tvldepot but aren't upstream:
1. The ability to just specify usernames rather than email addresses
2. The ability to specify `group:GROUPNAME`, _as long as_ that group is
visible to everyone. This is a restriction intended to avoid having
the plugin just leak group membership.

Using rust's PartialEq trait to implement Nix equality semantics is
reasonably fraught with peril, both because the actual laws are
different than what nix expects, and (more importantly) because certain
things actually require extra context to compare for equality (for
example, thunks need to be forced). This converts the manual PartialEq
impl for Value (and all its descendants) to a *derived* PartialEq
impl (which requires a lot of extra PartialEq derives on miscellanious
other types within the codebase), and converts the previous
nix-semantics equality comparison into a new `nix_eq` method. This
returns an EvalResult, even though it can't currently return an error,
to allow it to fail when eg forcing thunks (which it will do soon).
Since the PartialEq impls for Value and NixAttrs are now quite boring,
this converts the generated proptests for those into handwritten ones
that cover `nix_eq` instead

`import` will need to carry an `Rc<RefCell<CodeMap>>` (or maybe, in

files at runtime.
Note that the choice of `Arc` over `Rc` here is not ours - it's the
