Jade Lovelace 817322fbfb Document ExprLambda fields
We got confused what formals did and had to briefly figure it out. We
should just have docs, so these are some.

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.

Without this, the Meson setup won't bail out if nlohmann_json is

sure).

    own line.

This is UB, we should not be doing it, and we can cheaply turn it into

doing something silly.

Benchmarks, but i wonder if they are nonsense because they get identical
times across compilers?!

jade ffbad9b762 progress-bar.cc: fix signed overflow
this was caused by the use of std::chrono::duration::max() which gets
multiplied by some ratio to calculate nanoseconds to wait. then, it
explodes because that is a signed integer overflow. this was definitely
a bug.

Qyriad 038daad218 meson: implement functional tests
Functional tests can be run with
`meson test -C build --suite installcheck`.

Notably, functional tests must be run *after* running `meson install`
(Lix's derivation runs the installcheck suite in installCheckPhase so it
does this correctly), due to some quirks between Meson and the testing
system.

As far as I can tell the functional tests are meant to be run after
installing anyway, but unfortunately I can't transparently make
`meson test --suite installcheck` depend on the install targets.

The script that runs the functional tests, meson/run-test.py, checks
that `meson install` has happened and fails fast with a (hopefully)
helpful error message if any of the functional tests are run before
installing.

TODO: this change needs reflection in developer documentation

jade edba570664 HOT SALE: 15% off your build times!
This was achieved by running maintainers/buildtime_report.sh on the
build directory of a meson build, then asking "why the heck is json
eating our build times", and strategically moving the json using bits
out of widely included headers.

It turns out that putting literally any metrics whatsoever into the
build had immediate and predictable results.

Results are 1382.5s frontend time -> 1175.4s frontend time, back end
time approximately invariant.

eldritch horrors 279e30e7ef build: replace changelog-d with local script
hacking changelog-d to support not just github but also forgejo and
gerrit is a lot more complicated than it's worth, even moreso since
the entire thing can just as well be done with ~60 lines of python.
this new script is also much cheaper to instantiate (being python),
so having it enabled in all shells is far less of a hassle.

we've also adjusted existing release notes that referenced a gerrit
cl to auto-link to the cl in question, making the diff a bit bigger
