Implement the main function for the new, proto-based nix daemon. This
mostly replicates the behavior of the previous nix daemon - it starts a
grpc server listening on the same nix socket path and supports the same
set of options - with the exception of --stdio, which has been renamed
to --pipe and documented in the man page.

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

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

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.
