7c56fccdad feat(3p/nix): Template systemd unit files in build
Template the systemd unit file templates as part of the nix
installPhase, putting them in the same place that the upstream nix
derivation does.

2f85dfe50c fix(3p/nix): Don't include depotPath in the main drv
Including depotPath in the shellHook of the main derivation for tvix
was, unsurprisingly, causing spurious rebuilds. It's still useful when
developing locally, though, so I've extracted it to a `build-shell`
derivation as a passthru attribute and updated the documentation.

Fixes: #20

b8e94002d6 feat(3p/nix): run clang-tidy during builds
We need to -isystem the libcxx header files in order for clang-tidy to ignore them, as the Nix clang toolchain isn't doing that automatically.

This is the easiest way to get the checks up and running for now, but
we will probably want to separate out things like this into a separate

61a7b97c39 test(3p/nix): Enable output comparison for evaluator success tests
Enables loading of the expected output of evaluator tests from the
corresponding .exp files, and checks that the output matches.

This again leaves some tests behind in the disabled folder, but we now
have almost the entire suite up and running so I can get around to
cleaning up the disabled ones.

Other note: Some tests had XML output, despite not being related to
XML testing at all - I'm not sure why they chose to do this, but have
converted those test outputs to normal Nix instead.

We have a separate test suite for JSON & XML serialisation already,
which was contributed by andi-.

54a5750770 test(3p/nix): Add property tests for attribute set
Add a set of property tests for the attribute set (Bindings) class
checking that the Merge operation satisfies the monoid laws. This
will hopefully become useful to make sure we're not breaking the
language semantics as we work towards optimizing or replacing the
implementation, but also serves as a test bed for adding
rapidcheck-based property tests to the codebase.

cbea59c5f6 chore(3p/nix): don't rebuild nix-proto-srcs as much
Interpolating a path into a string will copy the referenced path into
the Nix store, so this got a dependency on all of src.  By first
constructing a path to the src/proto directory using the + operator,
and then interpolating it, we limit what is copied to the store, and
therefore what code triggers a nix-proto-srcs rebuild.

f4f72bcf21 test(3p/nix): Set up scaffolding & fix up tests for value-to-{json|xml}
Configures the CMake build to load & run the GoogleTest tests.

I (grfn) also updated this to get the tests running as part of the nix
derivation, which required defining our own manual configurePhase and
installCheckPhase, rather than depending on the one provided by stdenv.
Not doing this would cause cmake to attempt to *run* the tests as part
of the buildPhase, which wouldn't work because the dynamic libraries
hadn't been put into a place where the test executables knew where to
find them. We're not sure *why* this fixes it, and for some reason
fixing this also breaks the automatic behavior of nixpkgs of passing
-j$NIX_BUILD_CORES -l$NIX_BUILD_CORES to make, but that's eaasy enough
to fix manually in a preBuild

9a4a4058a8 style(3p/nix): Rename the project to tvix
Changes the derivation name & README overview to say "Tvix" instead of
"tazjix".

The previous name was mostly intended as a joke, and a way for me to
distinguish output paths. It's certainly not the intention to have a
portmanteau with my name here, especially now that several people are
contributing to the fork.

0064e55486 feat(3p/nix): Add protobuf & gRPC dependencies and generate sources
Adds dependencies on the gRPC & protobuf libraries, and implements Nix
code to generate the C++ sources from the included proto definitions.

This is theoretically supported via CMake, but practically doesn't
work and I don't care to debug why.

Doing it like this lets us instead add a CMake library target for our
proto definitions based on the sources generated by Nix.

Pros:
  * no need to deal with the gRPC CMake mess
  * it works!

Cons: * iteration requires nix-shell restart

5cb6e6ee21 fix(3p/nix): Link to Abseil built by Nix
This didn't work previously ... but now it does. I think setting the
standard explicitly is what did the trick, but it's slightly unclear
to me why.

Either way this means that Abseil is no longer constantly getting
recompiled when building Nix, which is nice.

25393d8080 refactor(3p/nix): Introduce CMake as the build system for Nix
Completes the switch from Meson to CMake for the core build system in
Nix.

Meson was added originally because someone else had already done the
work for integrating it in Nix and it was an upgrade from the previous
setup.

However over time it became clear that Meson is not quite mature
enough for projects like Nix that have occasionally peculiar
configuration constraints.

Some issues encountered with Meson (some of these are due to the Meson
setup in Nix):

* Difficulty with generating correct compile_commands.json for
  external tools like clangd
* Difficulty linking to libc++ when using clang
* Ugly shell invocations for certain parts of the build system (I want
  these to be gone!!!)

This CMake setup mimics the Meson configuration, but there are some
differences (some temporary):

* headers are now included separately for each library (see a previous
  commit that changes includes appropriately)
* autoheaders-style configuration is currently hardcoded. Before
  blindly copying this I want to evaluate how much of it actually exists
  for portability concerns that I don't have (such as support for OS
  X).
* Nix is built with libc++ by default.
* [libstore] SQL schema is now inlined via a generated header, not an
  included string literal

Abseil is still built as part of this build, rather than an external
dependency, because it chokes on differently configured compiler
invocations.

Note that because of the move to libc++ an unwanted behaviour is
introduced: glog log messages no longer have a body. I have yet to
debug what is going on there.
