Qyriad 07e1ddc23d meson: add missing tests: ca, dyn-drv, plugins, libstoreconsumer

Rebecca Turner 0fec7d2db6 Rename some parse failure tests to parse-fail-*
These were mistakenly labeled `eval-fail-*`.

Note that the `lang.sh` runner passes `parse-fail-*` tests on stdin, so
filenames are removed from error messages.

Qyriad c355354772 docs: replace sed invocation with an mdbook preprocessor for @docroot@
We're not entirely clear on why the links preprocessor has to be done
*before* rather than after, but we assume it is probably that as a
builtin preprocessor it does some processing on the raw book source,
and not just the JSON data.

Also a real use for Python pattern matching? I know I was surprised too.

Qyriad 9166babbaf Revert "meson: move nix3 manpage generation into command-ref/"
This reverts commit 70954233743a233744787103d3211237a28ddbca.

This seems to have broken running ninja on warm build directories, which
is not what we want. Reverted until we figure out something better

Lunaphied 7a1054fa5f repl: improve :doc builtin repl command to support lambdas.
For a long time `nix repl` has supported displaying documentation set on
builtins, however, it has long been convention to use Markdown comments
on Nix functions themselves for documentation. This exposes that
information to `nix repl` users in a nice and formatted way.

NixOS/rfcs#145 doc-comments are primarily what this feature is intended
to consume, however, support for lambda documentation in the repl is
experimental. We do our best effort to support the RFC here.

These changes are based on [the nix-doc library](https://github.com/lf-/nix-doc) and
are licensed under the terms described in the relevant source files.

eldritch horrors 45623f077f libutil: drop Fs{Source,Sink}::good
setting this only on exceptions caused by actual fd access is not
sufficient to diagnose all errors (such as SerialisationError) in
some cases. this usually does not have any negative effects since
those errors will end up killing the process in another way. this
is not a reliable assumption though and we should be using proper
error handling (and closing connections more often, preferring to
close over keeping something open that might be in a weird state)

eldritch horrors f402c45cfa libutil: allow graceful dropping of Pool::Handle
not needed yet, but returning a resource from the exception handling
path that has ownership of a handle is currently not well-supported.
we could also add a default constructor to Handle, but then we would
also need to change the pool reference to a pointer. eventually that
should be done since now resources can be swapped between pools with
clever moves, but since that's not a problem yet we won't do it now.

eldritch horrors 2d3fd6b9ab libstore: using throwing finally in withFramedSink
the duplication of exception handling was added without justification,
so we can only assume that it was done like this because Finally could
not throw exceptions safely. since this has now been rectified we will
deduplicate this handler code again.

eldritch horrors dd06f9b792 libutil: make ~Finally noexcept(false)
this is supposed to act like a finally block does in other languages. a
finally block should be able to throw exceptions of its own rather than
just crashing the entire program when it throws it own exceptions. even
in the rare case of a finally throwing an unexpected exception it might
be better to report the exception from Finally instead of the original,
at least that can keep our program running instead of letting it crash.

eldritch horrors 0b6d353474 libutil: remove Pool::Handle::bad
it was used incorrectly (not swapped on handle move), only used in one
place (that is now handled with exception handling detection in Handle
itself), and if ever reintroduced should be replaced with a different,
more understandable mechanism (like an explicit dropAsInvalid method).

eldritch horrors 620de98d0c libutil: drop Pool resources on exceptional free
if a scope owning a resource does not gracefully drop that resource
while handling exceptions from deeper down the call stack we should
assume the resource is invalid state and drop it. currently it *is*
true that such cases do not cause resources to be freed, but thanks
to validator misuses this has so far not caused any larger problem.

Qyriad 2041bdac2d perl: put perl dependencies in buildInputs instead of manually passing them to configure
Perl has an env hook[1]. Passing the paths manually without putting them
in buildInputs is harder to understand, plays less nicely with dev
shells, and is less build-generic.

Produced identical output on my x86_64-linux machine, and on my
aarch64-darwin machine was identical save for the derivation output path
which gets embedded into the .dylib Mach-O.

jade 99f159c536 Add basic clang-tidy config
This has not yet had all the warnings Obliterated, but it is a start and
is not *super* far away from being able to run the current configuration
in CI, which will catch some limited number of mistakes.

I tried the meson clang-tidy target and it seems to fail to find flags
for several files, which seems broken. Unsure what is up with that, but
we can use run-clang-tidy or other tooling instead.

We have an extremely annoying situation with the lexer table, which
means that the lexer probably must be moved to another directory with
its own .clang-tidy file to disable the lints in it, *or* write scuffed
code that prepends a disable comment to the top of the generated file.
None of the comment-based lint disabling features work since yacc dumps
a bunch of non compliant code at the top of the file before anything the
user can control.

  its intended purpose.
