Documents some of the weirdness of __curPos and the or keyword.
This does not fit well into any existing section for either of
them, though the use of or as a quasi-operator is mentioned in
the section on operators.

grepQuietInvert is a typo introduced by c11836126b.
The test functional-timeout was failing silently because Bash considered
the command-not-found error as truthy.

If a nested nix-shell is run inside a nix-shell, then the outer shell's
shellHook will be passed through and run again, unless the nested shell
defines its own.
With lix's hook, this can be annoying: forgetting to exit its nix-shell,
cd'ing to another repository & entering a nested nix-shell will happily
install lix's pre-commit hook in it.
This change makes lix's hook return early in such cases.

According to doc/manual/src/contributing/hacking.md, all development
shells should also be available in classic nix using the -A argument
to nix-shell, e.g.
nix-shell -A native-clangStdenvPackages
This was not actually the case; flake-compat generates attrsets like
nix-shell -A devShells.x86_64-linux.native-clangStdenvPackages
instead. These are unwieldy to use, so rather than changing the docs,
this changes the shell.nix file to result in the documented behavior.

check goals for timeouts first, and their activity fds only if no
timeout has occurred. checking for timeouts *after* activity sets
us up for assertion failures by running multiple build completion
notifiers, the first of which will kill/reap the the goal process
and consuming the Pid instance. when the second notifier attempts
to do the same it will core dump with an assertion failure in Pid
and take down not only the single goal, but the entire daemon and
all goals it was building. luckily this is rare in practice since
it requires a build to both finish and time out at the same time.
writing a test for this is not feasible due to how much it relies
on scheduling to actually trigger the underlying bug, but on idle
machines it can usually be triggered by running multiple sleeping
builds with timeout set to the sleep duration and `--keep-going`:
nix-build --timeout 10 --builders '' --keep-going -E '
with import <nixpkgs> {};
builtins.genList
(i: runCommand "foo-${toString i}" {} "sleep 10")
100
'

8c06b7b43¹ made libfetchers log the URL being fetched just before the
actual fetch, particularly in case something freezes. This used the base
URL, to not include query parameters, as the Nixpkgs lib tests assume
that stderr logs will be equal across shallow and non-shallow git
fetches (and shallow fetches have the ?shallow=1 query parameter).
8c06b7b43 assumed that the `base` field of ParsedURL would be populated,
as the comment simply says "URL without query/fragment"... but
apparently it is not populated when the URL being fetched is *already*
fetched, which caused libfetchers to log things like
fetching gitlab input ''
which is. silly. but you know, busted lix be busted.
Anyway, with this commit we just remove the query params before printing
instead, which seems to do the right thing

The `builder` local variable and duplicate `args.push_back` are no
longer required since the Darwin sandbox stopped using `sandbox-exec`.
The `drv->isBuiltin` check is not required either, as args are not
accessed when the builder is builtin.

Seccomp filtering and the no-new-privileges functionality improve the security
of the sandbox, and have been enabled by default for a long time. In
#265 it was decided that they
should be enabled unconditionally. Accordingly, remove the allow-new-privileges
(which had weird behavior anyway) and filter-syscall settings, and force the
security features on. Syscall filtering can still be enabled at build time to
support building on architectures libseccomp doesn't support.

`meson test` refuses to let `--verbose` (which shows the entire
invocation and stdio) override `--quiet`, but if neither are specified
in the justfile then you can use either `just test -q` or `just test -v`

Embarrassingly, I submitted a CL overriding submit requirements since
I thought it was spurious failures. However, the CI failure was in fact
real, and I have hopefully learned my lesson. The CI failure is that:
```
vm-test-run-nix-upgrade-nix> machine # installing 'nix-2.18.1'
vm-test-run-nix-upgrade-nix> machine # building '/nix/store/2b6fdf7wvahd00bg2ff0393bhd597a0h-user-environment.drv'...
vm-test-run-nix-upgrade-nix> machine # error: Unable to build profile. There is a conflict for the following files:

```
This is definitely caused by the pname not being the same, so we had
better revert that part of the change until we know we won't regress
anything by doing this.

* changes:
docs: linkify nix3-build mention in nix-build.md
build: make internal-api-docs PHONY
cleanup lookupFileArg
add docstring to lookupFileArg
add libcmd test for lookupFileArg
This breaks downstreams linking to us on purpose to make sure that if
someone is linking to Lix they're doing it on purpose and crucially not
mixing up Nix and Lix versions in compatibility code.
We still need to fix the internal includes to follow the same schema so
we can drop the single-level include system entirely. However, this
requires a little more effort.
This adds pkg-config for libfetchers and config.h.
Migration path:
expr.hh -> lix/libexpr/expr.hh
nix/config.h -> lix/config.h
To apply this migration automatically, remove all `<nix/>` from
includes, so: `#include <nix/expr.hh>` -> `#include <expr.hh>`. Then,
the correct paths will be resolved from the tangled mess, and the
clang-tidy automated fix will work.
Then run the following for out of tree projects:
```
lix_root=$HOME/lix
(cd $lix_root/clang-tidy && nix develop -c 'meson setup build && ninja -C build')
run-clang-tidy -checks='-*,lix-fixincludes' -load=$lix_root/clang-tidy/build/liblix-clang-tidy.so -p build/ -fix src
```

Since we're skipping Meson's dependency tracking, for the
internal-api-docs custom target, we should just consider it a phony
target and build it on every request.
