77205b2042 Allow for ergnomically putting Unix-only files in subdirs by creating INLCUDE_$(pkg) vars
Separate platform-specific files will allow avoiding a lot of CPP.

2625e9fb0a Ban building Nix with NDEBUG
When reviewing old PRs, I found that #9997 adds some code to ensure one
particular assert is always present. But, removing asserts isn't
something we do in our own release builds either in the flake here or in
nixpkgs, and is plainly a bad idea that increases support burden,
especially if other distros make bad choices of build flags in their Nix
packaging.

For context, the assert macro in the C standard is defined to do nothing
if NDEBUG is set.

There is no way in our build system to set -DNDEBUG without manually
adding it to CFLAGS, so this is simply a configuration we do not use.
Let's ban it at compile time.

I put this preprocessor directive in src/libutil.cc because it is not
obvious where else to put it, and it seems like the most logical file
since you are not getting a usable nix without it.

41dd9857c7 Proper parse and render functions for FileIngestionMethod and ContentAddressMethod
No outward facing behavior is changed.

Older methods with same names that operate on on method + algo pair (for
old-style `<method>:algo`) are renamed to `*WithAlgo`.)

The functions are unit-tested in the same way the names for the hash
algorithms are tested.

f1b4663805 Disallow store path names that are . or .. (plus opt. -)
As discussed in the maintainer meeting on 2024-01-29.

Mainly this is to avoid a situation where the name is parsed and
treated as a file name, mostly to protect users.
.-* and ..-* are also considered invalid because they might strip
on that separator to remove versions. Doesn't really work, but that's
what we decided, and I won't argue with it, because .-* probably
doesn't seem to have a real world application anyway.
We do still permit a 1-character name that's just "-", which still
poses a similar risk in such a situation. We can't start disallowing
trailing -, because a non-zero number of users will need it and we've
seen how annoying and painful such a change is.

What matters most is preventing a situation where . or .. can be
injected, and to just get this done.

1e24db6f9a Convert Machine::speedFactor from a non-neg int to a non-neg float
The short motivation is to match Hydra, so we can de-dup.

worker protocol: serialise cgroup stats in BuildResult (#9598)
By doing so, they get reported when building through the daemon via either `unix://` or `ssh-ng://`.

a5521b7d94 Factor out ServeProto::Serialiser<UnkeyedValidPathInfo> and test
In the process, partially undo e89b5bd0bf
in that the ancient < 2.4 version is now supported again by the
serializer again. `LegacySSHStore`, instead of also asserting that the
version is at least 4, just checks that `narHash` is set.

This allows us to better test the serializer in isolation for both
versions (< 4 and >= 4).

5334c9c792 HashType: Rename to HashAlgorithm
To be consistent with CLI, nix API
and many other references.

As part of this, we also converted it to a scoped enum.

91b6833686 Move tests to separate directories, and document
Today, with the tests inside a `tests` intermingled with the
corresponding library's source code, we have a few problems:

- We have to be careful that wildcards don't end up with tests being
  built as part of Nix proper, or test headers being installed as part
  of Nix proper.

- Tests in libraries but not executables is not right:

  - It means each executable runs the previous unit tests again, because
    it needs the libraries.

  - It doesn't work right on Windows, which doesn't want you to load a
    DLL just for the side global variable . It could be made to work
    with the dlopen equivalent, but that's gross!

This reorg solves these problems.

There is a remaining problem which is that sibbling headers (like
`hash.hh` the test header vs `hash.hh` the main `libnixutil` header) end
up shadowing each other. This PR doesn't solve that. That is left as
future work for a future PR.
