The order between receiving the STUN success and the triggered check is
not guaranteed, therefore resolve possible race condition by expecting
the two packets in either order.

The codec answer routine resets the codec storage and so also resets the
clock rate tracker for "touched" codecs. This leads to all codecs seen
as "not touched" in the answer routine, which in turn leads to
supplemental codecs present in the answer SDP that should not be there.
Use the "for transcoding" flag for previously present codecs to retain
the "touched" status across the codec answer routine.

When doing the initial answer, the packet_stream endpoint port isn't
filled in yet. Use the stream_params port instead to test for rejected
streams.

Since we're creating a dummy sfd to hold the SRTCP context when we don't
have an actual RTCP port, we must make sure to remember and re-use this
dummy sfd during a re-invite. Otherwise we end up creating a duplicate
dummy sfd, which is detected as a different sfd and thus triggers an ICE
restart.

Explicitly copy SDP up to the format list before printing it out. This
preserves broken input SDP.

Special handling for codec lists that were received as part of an
answer: If the list includes a codec that was not offered, ignore that
codec. This prevents transcoders from being set up that were not
requested.
This brought to light some tests that were actually broken.

Supplemental codecs such as DTMF use static timestamps while the event
is ongoing, leading to a TS jump when the RTP flow changes back to
audio. The sequencer needs to be aware of this so it doesn't mistakenly
see the next audio packet as overdue and starts to process it
prematurely.

These tests are timing sensitive which makes them unstable under certain
conditions. Remove them from the automated build system.

Complete overhaul of the codec handling code:
*) obsolete flags `asymmetric codecs`, `symmetric codecs`, `reorder
codecs`
*) support proper codec offer/answer
*) split codec manipulation (strip/offer/accept/etc) into separate
functions for clarity and better code maintenance
*) fully update codec handlers in both directions after an answer
*) explicit allocation and handling of codecs and payload types in a
codec_store object
*) improve codec matchup logic during answer
*) more explicit handling of supplemental codecs (CN/DTMF)
*) remove now obsolete hacks for handling certain use cases

Avoid using an explicit test for the trickle ICE endpoint address and
instead use the TRICKLE_ICE flag.
