Now called `UnitHash` and `Metadata`. The goal is to provide role-specific `UnitHash` accessors on the new `Metadata`. I chose this method, instead of changing the accessors on `CompilationFiles`, to have the least impact on the documentation as what is called `Metadata` can remain the focus of the documentation, rather than having it apply to different `CompilationFiles` accessors which don't house the actual logic.
We have - `-C metadata` - `-C extra-filename` - Uniquifying build scripts - Uniquifying scraped documentation The last two I'm tracking as a `unit_id`. As we evolve the first two hashes, we can decide which would be a better fit for backing this. For scraping, we could treat this as `-C extra-filename` but then we'd have a lot of `.expect()`s.

What does this PR try to resolve?
We have
-C metadata-C extra-filenameCurrently, these are all the same value. For #8716, we might want to have
-C metadataand-C extra-filenamehash different parts of theUnit. I figured that this change helps to clarify intent so that even if we don't change the definitions, this could still be worth it.The last two I'm tracking as a
unit_id. As we evolve the first twohashes, we can decide which would be a better fit for backing the
unit_id.For scraping, I could have treated this as
-C extra-filenamebut then we'd have a lot of.expect()s.I moved the accessors from
CompilationFilestoMetaInfoso we could closely associate the documentation, API, and implementation. MakingCompilationFiles::c_metadatathe main entry point that gets documented would be weird because the hashing is associated withMetaInfo(umbrella type, was private, nowMetadata) orMetadata(agnostic of each use, nowUnitHash)How should we test and review this PR?
