I was instructed to benchmark these functions, but I couldn't get the
benchmarking library to run using Nix -- although I'm *sure* it's
possible. Unfortunately the book recommends using `stack`, which I couldn't
reproduce.
The link here doesn't work, which is frustrating.

in the old daemon implementation, because they have very similar

These files were always implicitly depended upon by worker-protocol.hh, but just so happened also always be included in places where the other ones were already present.
We are likely getting rid of this file sooner rather than later, but in
the meantime this will cause clangd to shut up while I'm editing the
file.

Replaces the previous uses of the (ordered!) std::map and std::set
with absl::flat_hash_{map|set}.
After some careful reading it seems that there is actually no
ordering dependency on these types, and the (drop-in) replacements
perform slightly better.
Overall this is not fixing a bottleneck, just a driveby thing.

Several definitions of functions declared in eval.hh were previously
implemented in parser.y, this moves them over to parser.cc.
While this still isn't a reasonable place to keep them, the long-term
fix is more likely to be that eval.hh needs to be split up.
Before we get to that point however, this already gives us the ability
to use tooling with this code.

First step (of many?) towards extracting all the inline code from the
Yacc file and keeping it somewhere more accessible instead.
Note that none of this code has previously been touched by a linter or
formatter, pretty much ever, so as it is extracted it also undergoes
similar changes to the whole codebase after the initial fork.

Instead of manually iterating over the two bindings to be combined,
this adds a new static method on the Bindings class which merges two
attribute sets by calling the range insertion operator over them.
In some anecdotal tests, this can lead to a ~10% speed bump -
depending on the specific operation.

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.

On the chopping block this time:
* requests/responses that return one or more store paths, and contain
nothing else, have been changed to use the same types (StorePath and
StorePaths, respectively)
* QuerySubstitutablePathInfos has been added. It should be noted that
legacy Nix has two versions of this call, one that only queries a
single info (deprecated) and one that queries multiple. We have only
implemented the latter.
* QueryDerivationOutputs has been added.

This makes two main changes:
1) It disables profiling of things that aren't part of the invoked
process (-a). This isn't particularly useful in most cases because
it will show things like Chrome's VP9 decoding while you're
profiling something else.
2) It tells perf about the debug symbol format, which for some reason
isn't DWARF2 by default.
