jack: Add new connection mode

Browse source 
Add a new connection mode to jacksrc and jacksink. In this new auto-force
connection mode jack will create as many ports as requested/needed in the
pipeline and will then connect as many physical ports as possible, possibly
leaving some ports unconnected.

Also get rid of some leftover g_print.

Fixes #575284.
