Improve the understanding of arguments

This changeset introduces a better way to understand arguments
passed into call sites. The original logic was moved from
astroid.context.CallContext, which become only a container for
arguments and keyword arguments, to astroid.arguments.ArgumentInferator,
a new class for understanding arguments.
