docs: fix python nix-shell example (#10841) 
* docs: fix python nix-shell example

This Python code snippet depended on Python 2 which has been marked as insecure in 24.05.

I modernized the example so new users will not be surprised upon copying and pasting the snippet for exploration.

06be6812a6 Create and install a nix-util.pc 
Before, `-lnixutil` was just stuck in `nix-store.pc`, but that doesn't
seem so nice.

This prepares us to distribute `libnixutil` in a separate package if we
want, but it should be a good change either way. I suspect it wasn't
done before because libutil was an extra unstable interface, but I don't
think we need worry about that. *All* the C++ is less stable than the C
(or that's the goal at least).

For what it's worth, Lix also created this pkg-config file *en passant*
during their rename:

da82d67022 builtins.warn: Require string argument 
... so that we may perhaps later extend the interface.
Note that Nixpkgs' lib.warn already requires a string coercible
argument, so this is reasonable. Also note that string coercible
values aren't all strings, but in practice, for warn, they are.

This doesn't switch to auto-deriving the fields, but by defining `<=>`
we allow deriving `<=>` in downstream types where `Hash` is used.

68090d7ff1 Fix empty outputsToInstall for InstallableAttrPath 
Fixes assertion failure if outputsToInstall is empty by defaulting to the "out"
output. That is, behavior between the following commands should be consistent:

	$ nix build --no-link --json .#nothing-to-install-no-out
	error: derivation '/nix/store/eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee-nothing-to-install-no-out.drv' does not have wanted outputs 'out'

	$ nix build --no-link --file default.nix --json nothing-to-install-no-out
	error: derivation '/nix/store/eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee-nothing-to-install-no-out.drv' does not have wanted outputs 'out'

Real-world example of this issue:

	$ nix build --json .#.legacyPackages.aarch64-linux.texlive.pkgs.iwona
	error: derivation '/nix/store/dj0h6b0pnlnan5nidnhqa0bmzq4rv6sx-iwona-0.995b.drv' does not have wanted outputs 'out'

	$ git rev-parse HEAD
	eee33247cf6941daea8398c976bd2dda7962b125
	$ nix build --json --file . texlive.pkgs.iwona
	nix: src/libstore/outputs-spec.hh:46: nix::OutputsSpec::Names::Names(std::set<std::__cxx11::basic_string<char> >&&): Assertion `!empty()' failed.

e0b159549b Misc Windows fixes 
1. Fix build by making the legacy SSH Storey's secret `logFD` setting
   not a setting on Windows. (It doesn't make sense to specify `void *`
   handles by integer cross-proccess, I don't think.)

2. Move some files that don't need to be Unix-only anymore back to their
   original locations.

Merge pull request #10812 from Mic92/build-perf 
Remove 100s of CPU time (10%) from build times (1465s -> 1302s)

473d2d56fc Remove 100s of CPU time (10%) from build times (1465s -> 1302s) 
Result's from Mic92's framework 13th Gen Intel Core i7-1360P:

Before: 3595.92s user 183.01s system 1360% cpu 4:37.74 total
After: 3486.07s user 168.93s system 1354% cpu 4:29.79 total

I saw that boost/lexical_cast was costing about 100s in CPU time on our
compiles. We can fix this trivially by doing explicit template
instantiation in exactly one place and eliminating all other includes of
it, which is a code improvement anyway by hiding the boost.
