Add functions to manipulate pmdepend_t objects 

We didn't have a free function before, causing some memory leaks. We also
need a dup function now that strings are not in the structure but are
dynamically allocated.

Also adapt pmdepmissing_t to use a pointer to a depend struct instead of an
inclusive one so we can use the functions we created here.
