nixery.dev uses the vnd.docker.container.image.v1 format, which is
recognized by the OCI [1] and originally defined by Docker [2]. The
config field in this image format, which this commit is about, is
even portable between the Docker and OCI formats (the Docker Golang
library embeds the OCI definition [3]).
The attribute names in what's called ImageConfig in [3] are specified as
PascalCase, which effectively means that the names Env and Cmd used by
nixery need to be capitalized. The lowercase variant is not causing a
lot of issues because most container tooling is written in Golang, which
allows case-insensitive matches when deserializing JSON. Languages that
parse strictly either miss the configuration values, or fail due to
unknown attributes. This commit capitalizes Cmd and Env to accomodate
strict parsers.

Previously, Nix strings were represented as a Box (within Value)
pointing to a tuple of an optional context, and another Box pointing to
the actual string allocation itself. This is pretty inefficient, both in
terms of memory usage (we use 48 whole bytes for a None context!) and in
terms of the extra indirection required to get at the actual data. It
was necessary, however, because with native Rust DSTs if we had
something like `struct NixString(Option<NixContext>, BStr)` we could
only pass around *fat* pointers to that value (with the length in the
pointer) and that'd make Value need to be bigger (which is a waste of
both memory and cache space, since that memory would be unused for all
other Values).
Instead, this commit implements *manual* allocation of a packed string
representation, with the length *in the allocation* as a field past the
context. This requires a big old pile of unsafe Rust, but the payoff is
clear:

Performance has improved.
Fortunately this change can be localized entirely within

Using an actual store path here means we have to copy all of depot into
the Nix store just to rebuild NixOS for a system - this is especially
painful if, like me, you have a rust target/ directory in depot which is
hundreds of GB - nix-build just OOMed on my system with 128GB of RAM!
There's no reason to use a store path here - we can just point to

We add a new set of builtins called `import_builtins`, which
will contain import-related builtins, such as `builtins.path` and
`builtins.filterSource`. Both can import paths into the store, with
various knobs to alter the result, e.g. filtering, renaming, expected
hashes.
We introduce `filtered_ingest` which will drive the filtered ingestion
via the Nix function via the generator machinery, and then we register
the root node to the path info service inside the store.
`builtins.filterSource` is very simple, `builtins.path` is a more
complicated model requiring the same logic albeit more sophisticated
with name customization, file ingestion method and expected SHA-256.

Think about an object store implementation. The client is doing a

By documenting the fact we don't need to support looking up intermediate
Directory messages, we can just batch all directories into the same

That's one possible abstraction to drive builds.
Whenever IO into a store path is requested, we look up the root node,
and in case we don't have it in PathInfoService, but KnownPaths gives us
a Derivation for that output path, trigger a build and await the result.
This recursively might trigger builds for parent paths if they haven't
been built yet.
Another option would be to simply expose a PathInfoService interface for
a builder too, and loop all building into IO via PathInfoService
composition - but let's start with something.
Note tvix-cli doesn't have a configurable BuildService yet, it's plugged
to the DummyBuildService, so whenever it needs to do a build, it'll fail,
but that's how it can be provoked:
```
(builtins.readFile (import <nixpkgs> {}).hello.outPath + "/bin/hello")
[…]
error[E029]: I/O error: /nix/store/cg8a576pz2yfc1wbhxm1zy4x7lrk8pix-hello-2.12.1: builds are not supported with DummyBuildService
--> [code]:1:2
|
1 | (builtins.readFile (import <nixpkgs> {}).hello.outPath + "/bin/hello")
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
```
Note how this fails, while pure output path calculation
(`(import <nixpkgs> {}).hello.outPath + "/bin/hello")`) still succeeds.
