7ef71cd21f src/libexpr/primops.cc: parseDrvName: make documentation follow implementation
The documentation for `parseDrvName` does not agree with the implementation when
the derivation name contains a dash which is followed by something that is
neither a letter nor a digit.  This commit corrects the documentation to agree
with the implementation.

dc205c75a2 src/libexpr/primops.cc: correct definition for intersectAttrs
The current definition of `intersectAttrs` is incorrect:

> Return a set consisting of the attributes in the set e2 that also exist in the
> set e1.

Recall that (Nix manual, section 5.1):

> An attribute set is a collection of name-value-pairs (called attributes)

According to the existing description of `intersectAttrs`, the following should
evaluate to the empty set, since no key-value *pair* (i.e. attribute) exists in
both sets:

```
builtins.intersectAttrs { x=3; } {x="foo";}
```

And yet:

```
nix-repl> builtins.intersectAttrs { x=3; } {x="foo";}
{ x = "foo"; }
```

Clearly the intent here was for the *names* of the resulting attribute set to be
the intersection of the *names* of the two arguments, and for the values of the
resulting attribute set to be the values from the second argument.

This commit corrects the definition, making it match the implementation and intent.

Make sure that people who run Nix in non-interactive mode (and so don't have the possibility to interactively accept the individual flake configuration settings) are aware of this flag.

b3550d9179 libexpr/fetchurl.nix: allow __impure fetch
This commit adds an optional `__impure` parameter to fetchurl.nix, which allows
the caller to use `libfetcher`'s fetcher in an impure derivation.  This allows
nixpkgs' patch-normalizing fetcher (fetchpatch) to be rewritten to use nix's
internal fetchurl, thereby eliminating the awkward "you can't use fetchpatch
here" banners scattered all over the place.

a17ce0a8a9 Fix evaluation cache
98e361ad4c introduced a regression where
previously stored attributes were replaced by placeholders. As a
result, a command like 'nix build nixpkgs#hello' had to be executed at
least twice to get caching.

This code does not seem necessary for suggestions to work.

flakes: throw an error if follows-declaration for an input is invalid
I recently got fairly confused why the following expression didn't have
any effect

    {
      description = "Foobar";
      inputs.sops-nix = {
        url = github:mic92/sops-nix;
        inputs.nixpkgs_22_05.follows = "nixpkgs";
      };
    }

until I found out that the input was called `nixpkgs-22_05` (please note
the dash vs. underscore).

IMHO it's not a good idea to not throw an error in that case and
probably leave end-users rather confused, so I implemented a small check
for that which basically checks whether `follows`-declaration from
overrides actually have corresponding inputs in the transitive flake.

In fact this was done by accident already in our own test-suite where
the removal of a `follows` was apparently forgotten[1].

Since the key of the `std::map` that holds the `overrides` is a vector
and we have to find the last element of each vector (i.e. the override)
this has to be done with a for loop in O(n) complexity with `n` being
the total amount of overrides (which shouldn't be that large though).

Please note that this doesn't work with nested expressions, i.e.

    inputs.fenix.inputs.nixpkgs.follows = "...";

which is a known problem[2].

For the expression demonstrated above, an error like this will be
thrown:

    error: sops-nix has a `follows'-declaration for a non-existant input nixpkgs_22_05!

flake.cc: Make non-flake overrides sticky
Overrides for inputs with flake=false were non-sticky, since they
changed the `original` in `flake.lock`. This fixes it, by using the same
locked original for both flake and non-flake inputs.
