nix/why-depends: fix output of --precise
I haven't checked when this was exactly introduced, but on Nix 2.16 I
realized that the additional lines inserted when using `--precise` are
completely separated from the tree:

    nix why-depends /nix/store/ccgr4faaxys39s091qridxg1947lggh4-evcxr-0.14.2 /nix/store/b7hvml0m3qmqraz1022fwvyyg6fc1vdy-gcc-12.2.0 --precise --extra-experimental-features nix-command
    /nix/store/ccgr4faaxys39s091qridxg1947lggh4-evcxr-0.14.2
        → /nix/store/lcf37pgp3rgww67v9x2990hbfwx96c1w-gcc-wrapper-12.2.0
            → /nix/store/b7hvml0m3qmqraz1022fwvyyg6fc1vdy-gcc-12.2.0
    └───bin/evcxr: …':'}.PATH=${PATH/':''/nix/store/lcf37pgp3rgww67v9x2990hbfwx96c1w-gcc-wrapper-12.2.0/bin'':'/':'}…
        └───bin/cpp: …k disable=SC2193.[[ "/nix/store/b7hvml0m3qmqraz1022fwvyyg6fc1vdy-gcc-12.2.0/bin/cpp" = *++ ]] &&…

This is apparently because `std::cout` is buffered and flushed in the
end whereas the rest of the output isn't. The fix is rather simple, just
use `logger->cout` as it's already the case for the rest of the code.

This way we also don't need to insert additional newlines in the `hits`
map since that's something the logger takes care of.

Also added a small test to make sure that the layout of this is somehow
tested to reduce the risk of further regressions here.

John Ericson 9b908fa70a Factor out nix-defexpr path computation
Avoid duplicated code, and also avoid "on the fly" path construction
(which makes it harder to keep track of which paths we use).

The factored out code doesn't create the Nix state dir anymore, but this
is fine because other in nix-env and nix-channel does:

- nix-env: Line 1407 in this commit

Eelco Dolstra d9e7758f47 Don't require .tar/.zip extension for tarball flakerefs
Special-casing the file name is rather ugly, so we shouldn't do
that. So now any {file,http,https} URL is handled by
TarballInputScheme, except for non-flake inputs (i.e. inputs that have
the attribute `flake = false`).

John Ericson 6525265f46 LocalStore::verifyPath: Try to clarify data flow with more scopes
It was initially unclear to me which of these are temporary state for
the verify paths computation, and which of these are the results of that
computation to be used in the rest of the function. Now, it is clear,
and enforced.

John Ericson 2a5f5fbb17 LocalStore::verifyPath: Use StorePathSet for store local var
We don't care about non-store-paths in there (things like `.links`, are,
in fact, allowed). So let's just skip them up front and be more strongly
typed.

Add parseFlakeRef and flakeRefToString builtins (#8670)
Over the last year or so I've run into several use cases where I need to
parse and/or serialize URLs for use by `builtins.fetchTree` or
`builtins.getFlake`, largely in order to produce _lockfile-like_ files
for lang2nix frameworks or tools which use `nix` internally to drive
builds.

I've gone through the painstaking process of emulating
`nix::FlakeRef::fromAttrs` and `nix::parseFlakeRef` several times with
mixed success; but these are difficult to create and even harder to
maintain if I hope to stay aligned with changes to the real
parser/serializer.

I understand why adding new `builtins` isn't something we want to do
flagrantly. I'm recommending this addition simply because I keep
encountering use cases where I need to parse/serialize these URIs in
`nix` expressions, and I want a reliable solution.

John Ericson 6bc98c7fba Give queryPartialDerivationOutputMap an evalStore parameter
This makes it more useful. In general, the derivation will be in one
store, and the realisation info is in another.

This also helps us avoid duplication. See how `resolveDerivedPath` is
now simpler because it uses `queryPartialDerivationOutputMap`. In #8369
we get more flavors of derived path, and need more code to resolve them
all, and this problem only gets worse.

The fact that we need a new method to deal with the multiple dispatch is
unfortunate, but this generally relates to the fact that `Store` is a
sub-par interface, too bulky/unwieldy and conflating separate concerns.
Solving that is out of scope of this PR.

This is part of the RFC 92 work. See tracking issue #6316
