eldritch horrors a3dd07535c fix build test error count checks
with async runtime scheduling we can no longer guarantee exact error
counts for builds that do not set keepGoing. the old behavior can be
recovered with a number of hacks that affect scheduling, but none of
those are very easy to follow now advisable. exact error counts will
like not be needed for almost all uses except tests, and *those* had
better check the actual messages rather than how many they got. more
messages can even help to avoid unnecessary rebuilds for most users.

eldritch horrors 7f4f86795c libstore: remove Goal::key
this was a debugging aid from day one that should not have any impact on
build semantics, and if it *does* have an impact on build semantics then
build semantics are seriously broken. keeping the order imposed by these
keys will be impossible once we let a real event loop schedule our jobs.

eldritch horrors 1a52e4f755 libstore: fix build tests
the new event loop could very occasionally notice that a dependency of
some goal has failed, process the failure, cause the depending goal to
fail accordingly, and in the doing of the latter two steps let further
dependencies that previously have not been reported as failed do their
reporting anyway. in such cases a goal could fail with "1 dependencies
failed", but more than one dependency failure message was shown. we'll
now report the correct number of failed dependency goals in all cases.

eldritch horrors b6884388a1 add dedicated test for hash mismatch url reporting
the current test relies on derivation build order being deterministic,
which will not be a reasonable expectation for all that long any more.

jade d92712673b store: guess the URL of failing fixed-output derivations
This is a shameless layering violation in favour of UX. It falls back
trivially to "unknown", so it's purely a UX feature.

Diagnostic sample:

```
error: hash mismatch in fixed-output derivation '/nix/store/sjfw324j4533lwnpmr5z4icpb85r63ai-x1.drv':
        likely URL: https://meow.puppy.forge/puppy.tar.gz
         specified: sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=
            got:    sha256-a1Qvp3FOOkWpL9kFHgugU1ok5UtRPSu+NwCZKbbaEro=
```

nix3-build: show all FOD errors with --keep-going
Basically I'd expect the same behavior as with `nix-build`, i.e.
with `--keep-going` the hash-mismatch error of each failing
fixed-output derivation is shown.

The approach is derived from `Store::buildPaths` (`entry-point.cc`):
instead of throwing the first build-result, check if there are any build
errors and if so, display all of them and throw after that.

Unfortunately, the BuildResult struct doesn't have an `ErrorInfo`
(there's a FIXME for that at least), so I have to construct my own here.
This is a rather cheap bugfix and I decided against touching too many
parts of libstore for that (also I don't know if that's in line with the
ongoing refactoring work).

Closes #302

John Ericson 30dcc19d1f Put functional tests in tests/functional
I think it is bad for these reasons when `tests/` contains a mix of
functional and integration tests

 - Concepts is harder to understand, the documentation makes a good
   unit vs functional vs integration distinction, but when the
   integration tests are just two subdirs within `tests/` this is not
   clear.

 - Source filtering in the `flake.nix` is more complex. We need to
   filter out some of the dirs from `tests/`, rather than simply pick
   the dirs we want and take all of them. This is a good sign the
   structure of what we are trying to do is not matching the structure
   of the files.

With this change we have a clean:
```shell-session
$ git show 'HEAD:tests'
tree HEAD:tests

functional/
installer/
nixos/
```
