I'm not dead against it, I'll change it to struct ucm_port. Or actually
I changed it already before you got around to writing your reply :)

Well, the ports should never be removed from the dynarray anywhere else
than in port_free(), so that scenario should never occur...

If you insist that I should pass port_free() to pa_dynarray_new(), I'll
also have to change pa_dynarray_free(), because currently it doesn't
work correctly, if items are removed from the array inside the free
callback.
