6f04b653ae Move the streams concept into sdp_offer_answer 
This makes it easier to see that the tying of tracks
to streams affects only the SDP negotiation, and not
what's sent on the wire.

09bd9ba1f3 Allow transceivers to be not found in more cases. 
This fixes the case where a media section is rejected in an answer,
something that is done by SFUs, but not possible using transceiver.stop().

44d0dff7a9 Move the PeerConnection's usage pattern concept to its own file. 
This makes it easier to use it from multiple other modules.

b8ca2a18a5 count plan-b/unified-plan usage in SDP answers 
the UMA stats currently do not count services like Hangouts that
have "complex" SDP with multiple tracks only in the answer, not in the
offer. Note that this changes the definition of the existing metric.

This prevents having to have sdp_offer_answer depend on peer_connection
for the messaging functions.

After this CL, sdp_offer_answer is bigger than peer_connection.

75b9ab6751 Move have_pending_rtp_data_channel_ to sdp_offer_answer 
Also use accessors for the last few member variable references
in PeerConnection.

This completes removing the variable accesses from SdpOfferAnswerHandler
to PeerConnection.

38b768c588 Factor out the transceiver list into a separate object. 
This component is heavily referenced by both PeerConnection and
SdpOfferAnswerHandler; it's likely that it will end up in
SdpOfferAnswerHandler.

Encapsulation makes it easier to move around.
