bump hbb_common: end the ICE forwarder at gathering complete, drop the closes Drop covers

Browse Source 
hbb_common now closes the local-candidate channel when gathering
completes, so the controlled side's forwarder in spawn_webrtc_answerer
ends there, and its signaling connection to hbbs with it, instead of
sitting on a socket hbbs closed at 90s idle for the rest of the session.
It also keeps the reassembly buffer across fragmented frames.

Stream closes the WebRTC peer connection on drop (hbb_common b0b624d),
so the close_webrtc() calls in port_forward and io_loop that sat
immediately before a return or the end of scope did nothing Drop was
not about to do, while the comments beside them still said a bare drop
leaked the pc. Remove both.
