Prior to this CL, rollback did not restore FiredDirection and remote
streams were only sometimes restored. This resulted in not firing
ontrack if a track was rolled back and then added again on the same
transceiver.
Rollback also never performed OnTrack, which is incorrect because a
transceiver that goes from sendrecv to inactive will cause OnRemoveTrack
and if this is rolled back (so we become sendrecv again) then we need
OnTrack to fire.
This CL improves rollback's "memory", fires ontrack in Rollback() and
adds test coverage.
Needed to solve similar bugs in the Chromium layers as well:

Note: Some files came out wrong when iwyu was applied. These are not included.

Also add a function for accessing the list as internal transceivers
rather than accessing the proxy objects; this exposes where the
internal objects are accessed and where we need external references.
Used the new list function in sdp_offer_answer wherever possible.
Adds an UnsafeList function that is not thread guarded, so that the
job of rooting out those instances can be done in a later CL.

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.
