Progress on #13405, which asks for an explicit characterisation of the
equivalence relation like the one given here.
Also progress on #11895, because we're using the term "build trace
entry" instead of "realisation".
Mention #9259, a future work item.

This continues the work for formalizing our current JSON docs. Note that
in the process, a few bugs were caught:
- `closureSize` was repeated twice, forgot `closureDownloadSize`
- `file*` fields should be `download*`. They are in fact called that in
the line-oriented `.narinfo` file, but were renamed in the JSON
format.
We immediately use this in the JSON schemas for Derivation and Deriving
Path, but we cannot yet use it in Store Object Info because those paths
*do* include the store dir currently.
- Uses the more explicit `@ingroup` most of the time, to avoid problems
with nested groups, and to make group membership more explicit.
The division into headers is not great for documentation purposes,
so this helps.
- More attention for memory management details
- Various other improvements to doc comments
Per #7591, the `nix-store --gc --print-dead` command does not provide
any feedback about the amount of disk space that is used by dead store
paths. It looks like this has been the case since 7ab68961e (* Garbage
collector: added an option `--use-atime' to delete paths in...,
2008-09-17).
Update the nix-store documentation to remove the claim that this is
function that `nix-store --gc --print-dead` performs.
S3 buckets support object versioning to prevent unexpected changes,
but Nix previously lacked the ability to fetch specific versions of
S3 objects. This adds support for a `versionId` query parameter in S3
URLs, enabling users to pin to specific object versions:
```
s3://bucket/key?region=us-east-1&versionId=abc123
```
Instead of specifying env variables all the time
we can instead embed the __asan_default_options symbol
in all executables / shared objects. This reduces code
duplication.
Previously, Nix would not create a cache entry for substituted/cached
inputs
This led to severe slowdowns in some scenarios where a large input (like
Nixpkgs) had already been unpacked to the store but didn't exist in a
users cache, as described in https://github.com/NixOS/nix/issues/11228
Using the same method as https://github.com/NixOS/nix/pull/12911, we can
create a cache entry for the fingerprint of substituted/cached inputs
and avoid this problem entirely
