Artemis Tosini 9adefa9de4 flake: Add cmake to devShell
Meson fails to setup when cmake is not found.
Add cmake to the default devShell so meson build works.

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.

* some things that can throw are marked noexcept
  yet the linter seems to think not. Maybe they can't throw in practice.
  I would rather not have the UB possibility in pretty obvious cold
  paths.
* various default-case-missing complaints
* a fair pile of casts from integer to character, which are in fact
  deliberate.
* an instance of <https://clang.llvm.org/extra/clang-tidy/checks/bugprone/move-forwarding-reference.html>
* bugprone-not-null-terminated-result on handing a string to curl in
  chunks of bytes. our usage is fine.
* reassigning a unique_ptr by CRIMES instead of using release(), then
  using release() and ignoring the result. wild. let's use release() for
  its intended purpose.

jade 7ccf49c021 Delete autoconf generated code from tree
Since we don't have a ./configure checked in, it makes no sense to keep
any of these scripts since people are already going to be running
autoreconf anyway.

Plus they will be completely deletable when meson shows up.

This fixes `autoreconfPhase` causing git diffs.
