puck 272c2ff15f remove extraneous cache entry from github fetcher
This isn't necessary, as it's already covered by the tarball fetcher's
cache.

Alyssa Ross c1319831fb Fix exportReferencesGraph when given store subpath
With Nix 2.3, it was possible to pass a subpath of a store path to
exportReferencesGraph:

	with import <nixpkgs> {};

	let
	  hello = writeShellScriptBin "hello" ''
	    echo ${toString builtins.currentTime}
	  '';
	in

	writeClosure [ "${hello}/bin/hello" ]

This regressed with Nix 2.4, with a very confusing error message, that
presumably indicates it was unintentional:

	error: path '/nix/store/3gl7kgjr4pwf03f0x70dgx9ln3bhl7zc-hello/bin/hello' is not in the Nix store

Qyriad b81eec6ed5 build internal API docs with Meson
This commit adds the capability for building the Doxygen internal API
docs in the Meson buildsystem, and also makes doing so the default for
the internal-api-docs hydra job. Aside from the /nix-support directory,
which differed only by the hash part of a store path, the outputs of
hydraJobs.internal-api-docs before and after this commit were
bit-for-bit identical on my machine.

Qyriad 80bbfe2034 don't throw an exception for the trivial case of isStorePath()...
Previously if isStorePath() was called on anything other than a
top-level /nix/store/some-path, it would throw a BadStorePath exception.
This commit duplicates the absolutely trivial check, into
maybeParseStorePath(), and leaves exception throwing to
parseStorePath(), the function that assumes you're already giving a
valid path instead of the one whose purpose is to check if its valid or
not...

not be a good thing?

Qyriad a3be742bda binary tarball: include cacert in root paths
93cc06334 removed nss-cacert from the binary tarball, but they're
necessary for global compatibility (and for our installer). This is what
results in cacerts being in the default profile, so e.g. the daemon has
TLS certs without having to use the system ones.

There's a fallback behavior in the daemon script in case these wind up
missing from the profile, but we don't want to have to rely on that,
since the fallback fails if it doesn't recognize one of a handful of
distros.

eldritch horrors 725f5cd358 docs: redo content generation for mdbook and manual
manpages can be rendered using the markdown output of mdbook, the rest
of the manual can generated out of the main doc/manual source tree. we
still use lowdown to actually render manpages instead of eg mdbook-man
because lowdown does generate reasonably good manpages (though that is
also somewhat debatable, but they're a lot better than mdbook-man).

doing this not only lets us drastically simplify the lowdown pipeline,
but also remove all custom {{#include}} handling since now mdbook does
all of it, even for the manpage builds. even the lowdown wrapper isn't
entirely necessary because lowdown can take all wrapper arguments with
command line flags rather than bits of input file content.

This also implements running mdbook in Meson, in order to generate the
manpages. The mdbook outputs are also installed in the usual location.

Rebecca Turner 9e7e927837 Print top-level errors normally in nix repl
Previously, errors while printing values in `nix repl` would be printed
in `«error: ...»` brackets rather than displayed normally:

```
nix-repl> legacyPackages.aarch64-darwin.pythonPackages.APScheduler
«error: Package ‘python-2.7.18.7’ in /nix/store/6s0m1qc31zw3l3kq0q4wd5cp3lqpkq0q-source/pkgs/development/interpreters/python/cpython/2.7/default.nix:335 is marked as insecure, refusing to evaluate.»
```

Now, errors will be displayed normally if they're emitted at the
top-level of an expression:

```
nix-repl> legacyPackages.aarch64-darwin.pythonPackages.APScheduler

```

Errors emitted in nested structures (like e.g. when printing `nixpkgs`)
will still be printed in brackets.

to be /etc, and not $out/etc, so we separate out the place where shell
profile files are installed, which is the only other place sysconfdir is
at all used.

the release notes generation script isn't entirely functional right now
due to pre-commit hooks, but it's good enough for time being. we need a
better release process for notes anyway.

Rebecca Turner 727b43478c Add repl-overlays
Adds a `repl-overlays` option, which specifies files that can overlay
and modify the top-level bindings in `nix repl`. For example, with the
following contents in `~/.config/nix/repl.nix`:

    info: final: prev: let
      optionalAttrs = predicate: attrs:
        if predicate
        then attrs
        else {};
    in
      optionalAttrs (prev ? legacyPackages && prev.legacyPackages ? ${info.currentSystem})
      {
        pkgs = prev.legacyPackages.${info.currentSystem};
      }

We can run `nix repl` and use `pkgs` to refer to `legacyPackages.${currentSystem}`:

    $ nix repl --repl-overlays ~/.config/nix/repl.nix nixpkgs
    Lix 2.90.0

We found some header files that don't conform to the style guide.

The Lix style guide requests that header files:
- Begin with `#pragma once` so they only get parsed once
- Contain a doxygen comment (`/**` or `///`) containing `@file`, for
  example, `///@file`, which will make doxygen generate docs for them.

  When adding that, consider also adding a `@brief` with a sentence
  explaining what the header is for.
