Please read b/108 to make sense of this.
This gets rid of the explicit list of exposed packages from nixpkgs,
and instead makes the entire package set available at
`third_party.nixpkgs`.
To accommodate this, a LOT of things have to be very slightly shuffled
around. Some of this was done in already submitted CLs, but this
change is unfortunately still quite noisy.
Pay extra attention to:
* overlay-like functionality that was partially moved to actual
overlays (partially as in, the minimum required to get a green
build)
* modified uses of the package set path, esp. in NixOS systems
Special notes:
* xanthous has been disabled in CI because of issues with the Haskell
overlay
* //third_party/nix has been disabled because of other unclear
dependency issues
Both of these will be tackled in a followup CL.

In order to arbitrarily split netencode over multiple reads, we need
to make the parser completely streaming, so that it recognizes all
cases where it needs more input.
Luckily, this is fairly trivial, after working around a bunch of
overeager parsing.
The tricky part was the giant `alt`, where inner parsers would start
consuming input and thus become incomplete when they fail afterwards.
Sinc the format *always* starts the different types with one
discriminator char, we can use that to instantly return the parser and
try the next one instead.
The other tricky part was that lists and records would parse all inner
elements and then choke on the empty string after the last element,
because the inner parser would consume at least the descriminator, and
an empty string is always `Incomplete`. We wrap these into a small
combinator which plays nice with `many0` in that regard.

It turns out that mainly GNU coreutils exhibit this behaviour …

testRustSimple is intended to wrap rustSimpleLib and rustSimpleBin and
theoretically pkgs.buildRustCrate with { buildTests = false; } while
building and running their tests, making them fail if the tests don't
succeed.
This is implemented using nix.drvSeqL which is a perfect fit here:
* { buildTests = true; } only returns an output with the test binaries
and does not actually run the tests. With drvSeqL we can easily wrap
this derivation.
* { buildTests = true } doesn't contain anything other derivations want
to depend on, so it is an derivation output we don't want to have.
drvSeqL hides the tests derivation away and only requires us to build
it once.
* Usually drvSeqL has the issue that tests (or advantage) are not rebuilt
if the test derivation changes. This is no question in this case as
due to the embedded nature of Rust's test, both the derivation with
and without tests change anyways regardless of which part was changed.
Future work: Allow injecting other tests?
