jade ecfe9345cf build: limit clang-tidy concurrency and respect NIX_BUILD_CORES
Apparently it was impolite to lint with 128 jobs on our CI machine with
128 threads. Let's fix it.

jade 3775b6ac88 package: remove unused autotools code, empty file
I noticed there was some stuff setting configureFlags that definitely do
not do anything with meson, so let's rip them out.

As for the empty file, it was added when I was thinking I needed a fake
C++ target to convince meson to create the necessary dependencies. That
was not in fact possible so it should have never been committed.

jade 3daeeaefb1 build: implement clang-tidy using our plugin
The principle of this is that you can either externally build it with
Nix (actual implementation will be in a future commit), or it can be
built with meson if the Nix one is not passed in.

The idea I have is that dev shells don't receive the one from Nix to
avoid having to build it, but CI can use the one from Nix and save some
gratuitous rebuilds.

The design of this is that you can run `ninja -C build clang-tidy` and
it will simply correctly clang-tidy the codebase in spite of PCH
bullshit caused by the cc-wrapper.

This is a truly horrendous number of hacks in a ball, caused by bugs in
several pieces of software, and I am not even getting started.

I don't consider this to fix the clang-tidy issue filing, since we still
have a fair number of issues to fix even on the existing minimal
configuration, and I have not yet implemented it in CI. Realistically we
will need to do something like https://github.com/Ericsson/codechecker
to be able to silence warnings without physically touching the code, or
at least *diff* reports between versions.

Also, the run-clang-tidy output design is rather atrocious and must
not be inflicted upon anyone I have respect for, since it buries the
diagnostics in a pile of invocation logs. We would do really well to
integrate with the Gerrit SARIF stuff so we can dump the reports on
people in a user-friendly manner.
