Subject: Add resolve_depends(var, prefix) function to qmake

This function calculates the topological order of variables.
We will use it to determine which and in what order to link
module libraries.

The function is not tied to libraries/modules only, but requires
the variables to be ordered to have their dependencies in the
[prefix]<var>.depends subvariable.

Due to the recursive nature of the algorithm it was just much easier
to implement it directly in C++ rather than in a qmake-language
function.
