We always need to (re)set the ssrc_map_out SSRC, even for the input
context, as this SSRC is used to look up the receiving SSRC context,
where the appropriate RX stats are stored, including the payload type in
use.

All timers have been moved to their dedicated timer threads, making this
mechanism obsolete.
The only victim is the timeout handling for TCP control streams. Since
other TCP streams aren't using timeout handling either, and the TCP
control socket is barely used by anyone, we can live with not having a
dedicated timeout for these streams for now.

Transcoding is flow-specific, so it doesn't make sense to have a flag
for it in a call_media section. Instead we use the transcoding flag set
on the call_subscription objects (on subscribers), and set/unset a flag
on the monologue struct, depending on whether any media flows (going to
subscribers) have transcoding enabled.

Due to multiple threads polling all sockets for read events, it's
possible for one socket to receive a read event in one thread, then
immediately receive another read event in another thread, resulting in
two threads reading packets from the same socket at the same time.
While this is perfectly valid and correctly handled by mutex etc, it can
result in packets being processed out of order. In media passthrough
scenarios which don't do sequencing this can result in packets being
reordered.
Using a simple atomic counter we can ensure that only one thread is
reading from any one socket at a time.

Don't try to interpret or schedule DTMF packets if we're just doing RTP
passthrough.
Without tracking the seqencing and timestamping of the primary media
stream, we cannot actually schedule DTMF packets properly. Use the
presence of a defined output sequence number to make this determination.
The other case that uses a predefined output sequence number is when
media is coming from a pre-coded media player stream. The same thing
applies: These packets are already scheduled, so we can skip trying to
schedule them again.

Check globally left monologues (with associations left) after

This is needed to prevent cases, when a recursive call of the

- A is in progress of destorying
- B gets recursive call of `monologue_delete_iter()` and sees
that A has still one association left with C, which A simply
hasn't manage to remove yet.

This commit: 6f0ad0db0f
introduced an improved behavior of the call deconstruction
when dealing with multiple forked legs. But it also
introduced a regression related to TPCC related calls.
This is because it takes into consideration existing
`->viabranches`, which is not efficient in certain cases.
Instead, we just have to ensure, whether there are
other monologues of the call object, which are not directly
"visible" for this branch being cancelled (so they are not directly
associated to that), but they might have own associations
present, which means the call mustn't be globally destoroyed.
Change-Id: I630f2d88ef3b557af3a95816fc2703daccaff374
Upon calling the `monologue_delete_iter()`, we have to take into account
an amount of forked legs we have now entirely in the call.
