Protect selected_sfd with in_lock.
Protect RTCP sending with in_lock and out_lock as appropriate.
Has the odd side effect of RTCP reports expected in tests to be sent one
packet later than before.
Closes#1966
Probably fixes#1927

If dummy definition with no tag, algo etc.
just ignore it, otherwise not excluded
and is dangling in outgoing SDP.
Also add according test.

RFC says that annex B is the default in the absence of the annexb=no
format string. Consider the alias "G729a" as annex A.

With reuse-codecs, we still need to place the codec from the SDP into
our prefs list, even if it's already present, as the format options may
have changed. Update one affected test case.

This seems to be an acceptable and reliable way to detect RTCP
multiplexed with RTP, even if `a=rtcp-mux` wasn't advertised in the SDP.
Take the opportunity to clean up __streams_set_sinks() a bit by giving
the variables better names.

Use the correct media object (the source media) to obtain media-level i=
lines from. Adapt OSRTP output function to do the same.

Support the recvfrom() function. This requires also returning to address
(not just the port) from the tester's rcv() function to be useful, which
in turn requires updating a bunch of tests.

The codec `strip` option used to remove codecs not only from the
destination (offer to) monologue, but also from the source (offered by)
monologue. Change this to only affect codecs on the destination
(offering to) side. This fixes a problem of not being able to have
different `strip` options set for different branches.
As a side effect, this breaks existing use cases of using `strip` to
ignore codecs on the source monologue side. This functionality is
restored by adding `codec-ignore` in the following commit.

Add a couple of tests for the following cases:
- use both zero-connection + mode sendrecv flags
at the same time
- answerer puts on hold (instead of offerer)

Sendrecv mode flag controls whether the sendrecv
state is forced to sendrecv, instead of the default
one sendonly, in the SDP body going towards recipient
(the one who will receive the MoH media).
Is declared as: moh=[mode=sendrecv]
Can be useful for corner cases, where the remote side
wants to see sendrecv state for whatever reason,
when getting MoH media and hence also remain in sendrecv
state in regards of the MoH originator.
Must be advertised once during the session origination,
nd then will affect the SDP body as soon as SDP sendonly
body is received (from the behalf of one, who advertised MoH
capabilities).
Backwards compatibility: doesn't affect non-MoH calls.
And doesn't affect offer/answer exchanges within MoH calls,
which do not put the remote side on hold.
Additionally: introduce a common function for the MoH flags
handling: `call_ml_moh_handle_flags()`, which does all
the required iterations/checks for the whole bunch of flags
at once.
Additionally: previously existing MoH tests adopted.
Additionally: new test introduced to check the SDP content,
when using mode sendrecv flag.
Remark: this flag is not mutually exclusive with
the zero-connection MoH flag.

Zero-connection flag controls whether the connection
address offered in the SDP body going towards recipient
(the one who will receive the MoH media), is set
to all zeroes.
Is declared as: moh=[connection=zero]
Can be useful for older client implementations,
who want to see zeroed media when receiving sendonly
and getting put on hold.
Must be advertised once during the session origination,
and then will affect the SDP body as soon as SDP sendonly
body is received (from the behalf of one, who advertised MoH
capabilities).
SDP body recovers to the real IP addresses being inserted
into recipient's SDP, as soon as the media gets unheld.
Backwards compatibility: doesn't affect non-MoH calls.
And doesn't affect offer/answer exchanges within MoH calls,
which do not put the remote side on hold.
Additionally: previously existing MoH test adopted.
Additionally: new test introduced to check the SDP content,
when using zero-connection flag.

Introduced Music on Hold functionality:
- available only for the offer/answer model,
no other scenarios (publish, subscriber etc.)
are covered with it
- it gets advertised always at the beginning of
the call (original offer/answer exchange)
- can be added for both sides: offerer/answerer
- the one who advertises its MoH capabilities
with its SDP offer or answer, can later trigger
MoH using sendonly SDP and unhold remote
party using sendrecv SDP
- MoH covers only audio type of media sessions
- there is no specific selection of media sections
to be held, thus, if one audio media puts the
call on hold, the whole call is held
- list of parameters to be given when advertising
MoH capabilities: a sound source (file, blob or db source);
sendonly/sendrecv hold; zero-connection hold;
At least an audio file source must be given
- MoH cannot be mixed with the play media functionality,
the last one triggered will override previous one
- MoH must be unheld to stop the media being sent
towards a recipient, otherwise only a termination
of monologues will stop this packets stream
