During I'm reading through the code base to learn MBS, I found out some
typos and minor issues in some other docstrings, and I also found some
docstrings with extra informative description could make it easier to
understand the code.

Now we have good separation between runtime and buildtime dependencies:
If mmd has context, it is built artefact which supposed to have only one
dependency entry, we create solvable with real arch for it. Otherwise we
create multiple solvables with "src" arch.
In "src" solvables, "context" is a number which represents index in
dependencies array.
Stream is not included anymore in "evr" because it's incomparable.
Version is not included anymore in "name" because it's there just for
comparison, nothing more (it's not different module-stream).
As a side, add_requires/add_conflicts/add_provides were replaced with
non-deprecated add_deparray method.
With all this, we are ready to handle MMDs which have multiple elements
in dependencies (modulemd v2).

Conflicting with module(foo) is more than enough to make sure that we
will have only one copy of solvables providing it.

Previous version was assuming that number of alternatives is static
which is wrong, they can be appearing depending on solvables.
Also it was checking even impossible combinations (due to using
itertools.product).
Now we check only real possibilities.
