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.

This adds a trivial test case on the transitive lib in tests and builds
it by wrapping in with testRustSimple. This should check:
* testRustSimple doesn't change the output and other packages can just
use it as a normal dependency
* tests are built and executed

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?

This adds the star of NixCon 2017 from vuizvui, slightly reformatted and

run the tests of rustSimple{Lib,Bin} where the normal and the -tests
variant would have to be rebuilt if either the tests or the library /
executable itself changes.

Refactor assertEq and assertThrows to be implemented in terms of a more
generic assertBool to reduce code duplication and ease adding new assert
types.
To preserve meaningful error messages AssertResult is changed slightly:
nope-eq and nope-throw have been replaced by a single nope branch which
contains an AssertErrorContext which contains error information. To
implement an assert assertBoolContext (which is not exposed) can be
used: It takes an AssertErrorContext which is returned in case of an
error and a boolean determining whether the assert was successful.
The currently possible AssertErrorContext are:
* should-throw: error result of assertThrows, formerly nope-throw
* not-equal: error result of assertEq, formerly nope-eq

`Text` and `Binary` should be self-explaining, they just match on the

OneOf is cool, because it allows the user to match on the
result type of decoding `inner`, and give a list of values that should
be allowed as the result type (the associated type `A` in the
`Decoder` trait).

This fell out of us moving the `U::List` to a `Vec`.
I noticed that now we have deep recursion for `U`s, which originally
wasn’t intended; reverting to contain `&[u8]` might be a good
experiment, as long as the lists stay a `Vec<&'a [u8]`, which was the
thing preventing us from parsing lists without allocating memory.

In order to implement this, either we’d have to introduce a type-level

just concatenated netencode values. But I noticed that you can’t write
e.g. a `t_to_u` function, because only in the case of lists you need
to allocate memory.
Turns out that if we read the next level of values, everything is
handled the same as in `Record` and things suddenly start working.
We can also throw away some of the strange and ad-hoc parser helpers
we needed before, `skip` and `list_take`, since now those are just
normal `Vec::iter().skip()` and take.

Nix internally differentiates between lambdas and primops, but their
type in the nix expression language is the same (lambda). The
implementation of builtins.functionArgs only checks if the given
expression is of type tLambda and fails if the type is tPrimop or
tPrimopApp which are also functions. This most notably breaks
lib.generators.toPretty when called on a builtin making for example
yants fail if a primop is typechecked and an error message is
generated.
This fix generates an empty set for primops like for plain lambdas
and is based upstream commit b2748c6e99239ff6803ba0da76c362790c8be192.
Additionally we add to two tests:
* eval-okay-functionargs now includes a few test cases checking that
builtins.functionArgs always returns an empty set for builtins and
also works as expected for normal functions.
* eval-okay-types now also checks if builtins are functions.
Future work would be to make builtins.functionArgs work as users would
expect for builtins like builtins.fetchurl, builtins.fetchGit etc. which
take a set as an argument. These currently don't register as formal
arguments, but it would be an usability improvement at least if they
did.
