This makes it possible to specify the input & output types of the
binary_op macro. If only one type is specified, it is assumed that the
input and output types are the same.

Adds support for true, false & nil. These each come with a new

Introduces a new enum which represents the different types of possible
values, and modifies the rest of the existing code to wrap/unwrap
these enum variants correctly.
Notably in the vm module, a new macro has been introduced that makes
it possible to encode a type expectation and return a runtime error in
case of a type mismatch.

Without this fix we would keep parsing in the same precedence level
and get weird things like:

This one necessarily has to diverge more from the book than the
treewalk interpreter did, so some of this is expected to change, but
I'm happy with the rough shape.
Since we're reusing the old scanner, the compiler/parser struct owns
an iterator over all tokens with which the pull-scanner from the
bytecode chapters is simulated.

When a file is added to the depot tree that is picked up by read-tree,
but it’s not a function like ({...}: {}), `readTree` will fail on the
function application, leading to a bad error message.
We can do slightly better, by checking the type and throwing a nicer
trace message.
`assertMsg` is copied from `nixpkgs/lib/assert.nix`, since at this
point we don’t have a reference to the lib.
There is another evaluation failure that can happen, which is when the
function we try to call does not have dots; however, nix does not
provide any inflection capabilies for checking whether a function
attrset is open (`builtins.functionArgs` only tells us the attrs it
mentions explicitly). Maybe the locality of the error could be
improved somehow.

Previously, for types defined using typedef (like all primitive types)
type.checkType would return a boolean. This is largely fine since in
most places `type.checkToBool (type.checkType x)` or similar is used.
However, some functions actually take type.checkType up on the promise
that it returns a set of the form:
{
ok = <bool>;
err = <option string>;
}
This is the case for restrict which has checkToBool = v: v.ok; and will
generate a proper set except if `t.checkToBool (t.checkType v) == false`
in which case it will return t.checkType v. If t was a primitive type or
defined using typedef, previously `t.checkType v` would be a boolean
which meant as soon as (restrict …).checkToBool was called on a restrict
checkType result in cases where the wrapped type didn't match, an
unrelated error would be thrown:
nix-repl> with nix.yants; restrict "foo" (_: true) int "lol"
error: value is a boolean while a set was expected, at /home/lukas/src/depot/nix/yants/default.nix:38:39
This is fixed by making typedef return a proper set from checkType and
adjusting its checkToBool accordingly.
Unfortunately I don't think we can easily add test cases for this except
by using recursive nix or VM tests as there is no way to introspect
error messages.

Main motivation for this is to get the openldap update that fixes
10 CVEs: CVE-2020-36221 to including CVE-2020-36230. See also this
issue which lists them all: https://github.com/NixOS/nixpkgs/issues/113490
Someone should also redeploy whitby as soon as this lands in canon and
all build failures have been fixed.
Things done to resolve upstream breakages:
* grpc no longer takes abseil-cpp as an input, it has also been removed
in the override.
* Upgrade glittershark's kernel to 5.11 since the linuxPackages_5_9
attribute has been removed by upstream and the patch used by them is
available for 5.11 as well.
* The fixed output hash for third_patry.apereo-cas changed for some reason.
* Remove the pin of haskellPackages.vector from the haskell overlay. It
broke as the most recent version of vector in nixos-unstable no longer
depends on semigroups. This effectively updates vector from 0.12.1.2
to 0.12.2.0.
* Align two comments in tvix/libstore/worker-protocol.hh because the
updated clang-format now demands that.

Nix unfortunately has terrible escaping syntax: If something is an
escape sequence it does not know, like \0, it just swallows the
backslash and returns the second character (byte) as is (yes,
"\0" == "0" is true). This created the following bug in nixFileName
which should have resulted in at least a parse error: "(.*)\.nix" is
the same as "(.*).nix" which meant that nixFileName matched anything
that is at least 4 characters long and ends in "nix". This lead to
readTree creating double attributes when directories are involved or
attributes for non-nix files.
