Add support for dynamic target extraction in addition to prerequisites

This functionality is enabled with the depdb-dyndep --dyn-target option. Only
the make format is supported, where the listed targets are added as ad hoc
group members (unless already specified as static members). This functionality
is not available in the --byproduct mode.
