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

7e8a48c82c fix(3p/nix): Link to glog built by Nix
Same as cl/921, it seems that the trick to making this work is indeed
overriding the C++ standard used in the dependency.

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.

ec84fde6b1 fix(3p/nix): Revert "feat(3p/nix): Add installCheckPhase"
This reverts commit 368e8d1edd.

Reason for revert: Didn't mean to submit, and the phase is currently failing (which breaks the otherwise-functional derivation)

4de63f784c fix(3p/nix): propagate dependencies which are needed by people linking in nix
This includes absl, which we install into the output, and boost and the boehm GC,
which are moved to propagated deps.

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.

5f728cb428 feat(3p/nix): Add a derivation to launch clangd
This wrapper derivation (which assumes that the depot is available at
~/depot) can be used to actually get clangd working with
//third_party/nix.

In my setup I can launch this with M-x eglot, followed by

  env
    CLANGD_FLAGS='--compile-commands-dir=/home/tazjin/projects/nix-build'
    nix-shell -A third_party.nix --run 'nix-clangd' /home/tazjin/depot

00017ace04 feat(3p/nix): Wrangle Meson/Nix/CMake into (temporary) submission
Meson is unable to use CMake in Nix to determine the internal
structure of the Abseil libraries.

This commit adds an explicit list of most of the Abseil targets that
are relevant (so far) and bundles them into a list that is linked
together.

9dfdf16a8d fix(3p/nix): Fix build of derivation if cmake is present
cmake automatically runs a configure hook which breaks the build,
since this isn't actually a cmake project. This hook is now disabled.

Additionally Abseil's sources are linked to an absolute derivation
path when the build launches, as opposed to the relative path used for
development builds.

e2fad0f0d2 feat(3p/nix): Add Abseil as a CMAKE subproject to Meson
Yep.

This is accomplished by symlinking the sources into the location
expected by Meson for subprojects.

3908732181 style(3p/nix): Final act in the brace-wrapping saga
This last change set was generated by a full clang-tidy run (including
compilation):

    clang-tidy -p ~/projects/nix-build/ \
      -checks=-*,readability-braces-around-statements -fix src/*/*.cc

Actually running clang-tidy requires some massaging to make it play
nice with Nix + meson, I'll be adding a wrapper or something for that soon.
