Now type checks the resulting function values and allows mkMerge and co.
Also indicates that the type check is done in the function body

Without this patch merging options like
services.xserver.windowManager.xmonad.extraPackages
results in the evaluation error:
error: value is a list while a set was expected, at nixpkgs/lib/options.nix:77:23
With this patch we get the desired merging behaviour that just concatenates the
resulting package lists.

This reverts commit 4ff1ab5a56.
We need this to type options like:
services.xserver.windowManager.xmonad.extraPackages that specify functions that
take an attribute set containing packages / plugins and return a list containing
a selection of the values in this set.
The reason we need a dedicated type for this is to have the correct merge
behaviour. Without the functionTo type merging multiple function option
definitions results in an evaluation error. The functionTo type merges
definitions by returning a new function that applies the functions of all the
definitions to the given input and merges the result.

Regression introduced by 2e34288f0d.
The commit in question just used the "lib" attribute, but it wasn't in
scope. In addition to bringeng the lib attribute into scope, I also
removed the "with lib;", which should make sure that we get an error
when just parsing (nix-instantiate --parse) the Nix expression.

This reverts commit 2dbd08dcbd.
I've fixed the regression in 8a7a8442c1 and the rest of my
refactorings/improvements shouldn't affect the stability of the test.
This creates a symlink to lua.pc for every name of the file used by Arch:
For a version of Lua (for example, 5.4) we now have:
- lib/pkgconfig/lua.pc
- lib/pkgconfig/lua-5.4.pc
- lib/pkgconfig/lua5.4.pc
- lib/pkgconfig/lua54.pc
