To stop spurious warnings, we will stop this bizarre behavior of setting
empty values to impure environment variables.
On the warning side, we verify that the presence of the environment
variable.
The corresponding test is updated to "there is a warning" to "there is
no warning".

All impure environment variables are initialized as part of `initEnv()`
to an empty value if they are unset.
Whenever `NIX_SSL_CERT_FILE` is set, this cause a spurious warning.
Let's document it here as a test before we fix it.

CA tests have grown quite complicated and are hard to debug and
manoeuver for new needs.
They are a prime target for F2 migration and they were extremely
pleasant to write.
Most functionality is preserved or improved with additional behaviors
asserted on warnings and the full set of reports.

Instead of taking in a final argument `Value &` out parameter which it
writes to, it now returns its result

we already report errors that happen during reads via exceptions
rethrown from read. reporting errors during destruction too is a
source of confusion for users since these errors are not usually
relevant and just the decompressor thread reporting short reads.
shorts reads during shutdown are not an error, they're expected.

I could instead add the right braces or manually ensure the
XMLOpenElement destructor is run at the right time. Or I could just
write what I actually want to happen.
Fixes#1137.

This is a rebase of CL 1626 after the performance problems that blocked
that change are no longer an issue.

The pseudo-constructor `Value::mkFloat` would previously be called on an
default-constructed (under-initialized) `Value` to create a properly
initialized `Value` that represents a float. This change removes mkFloat
and constructs float `Value`s directly.

The pseudo-constructor `Value::mkStringMove` would previously be called
on a default-constructed (under-initialized) `Value` to create a
properly initialized `Value` that represents a string, reusing an
existing GC allocated Str. This change turns that method into a proper
constructor

it sometimes happens that one forgets to add `.run().ok()` to a command,
leading to things not actually being tested, potentially even slipping
though code reviews!
This commit adds a check at fixture teardown time, checking that all
commands have been run. Sadly, due to when this check happens, we cannot
add a test checking for this behavior

this includes tests that fail teardown when *skipped*, which confuses
the tap parser by reporting more tests than advertised in the header.
not sure what to do about this though, and it is better than nothing.

pytest-tap didn't get it right in combination with xdist. we need to
replace the reporter *completely*, which is just incredibly weird :/

The pseudo-constructor `Value::mkPath` would previously be called on an

This is not ca-derivations. We don't care about self-references or any of the
rewriting or stuff like that; if you want something like that, write
your user code so it figures out where it is.
The reason I want to do this is for integrating other build systems with
Lix: if you're importing something built *outside the store* with a
non-Nix build system, it makes no sense to put it in an input-addressed
path since it's not possible to come up with a derivation for it.
But you need *some* hash, so the output hashing is the most sensible option.
It is also nice because of not needing trusted user privileges to import
it, since the hash describes the exact contents of the output path.
We use this feature (implemented externally to Lix; this CL eliminates
that step) at Mercury to integrate buck2 with Nix on the output side: we
import things to the Nix store as ca paths with references.
These can then be consumed by Nix language with:
```
# Hack from https://git.lix.systems/lix-project/lix/issues/402#issuecomment-5889
path:
builtins.appendContext path {
${path} = {
path = true;
};
}
```

```

this requires some hacks to make error reports visible, but hey. it's
better than no progress reports at all, and successful runs no longer
spew huge amounts of useless log output onto the developer's terminal
