(cherry picked from commit 394ed2fc62)
While LWS explicitly allows usage of lws_callback_on_writable() from
other threads, for some reason there is no internal locking in place,
and so a concurrently running lws_service() can interfere with internal
structures, in particular if lws_service() is closing connections at the
same time as lws_callback_on_writable() is invoked.
The suggested approach of using lws_cancel_service() in combination with
the LWS_CALLBACK_EVENT_WAIT_CANCELLED callback and a user-kept queue is
not feasible, as we need to support LWS 2.x, which doesn't have
LWS_CALLBACK_EVENT_WAIT_CANCELLED.

Avoid calling lws_write() from threads other than the service thread, as
this might not be thread-safe. Instead store the values used for the
HTTP response headers in the websocket_output, then trigger a "writable"
callback, and finally do all the lws_write() calls from the service
thread.

Don't change to a new port for sendonly streams as this causes problems
with NAT. A device receiving a sendonly SDP with a new port won't send
any RTP to the new port, leading to a closed (non existent) NAT mapping.

(cherry picked from commit 6d7603e064)
The old port latching logic was simply to use the last (newest)
allocated endpoint_map. This turned out to be wrong, because the last
used socket on the monologue could have been one that was allocated
earlier (and older endpoint_map), as it can happen during repeated
re-invites. Add a new function to actually look for the correct
endpoint_map, matching the currently used socket, to make sure the port
doesn't change.

The SRTP decryption context is associated with the local socket. Use the
socket that a packet was actually received on for the decryption context
instead of using the one that it was expected to be received on.
Change-Id: Iddf400a440fc51b4afb370ec827f75e9626b2cfd
When a receiving socket doesn't match the socket we were expecting, make
sure that the receiving socket is actually one of the sockets we want to
use at this point before blindly switching the socket.
This fixes a race condition after a re-invite: A new set of sockets has
been opened, but an old/delayed RTP packet still arrives on one of the
old ports. In this case we don't want to switch the local socket.

1) Read dtxb->start while the lock is held (not strictly necessary as
the read should be atomic anyway)
2) Expect that dtxb->start can be larger than rtpe_now.tv
The latter can happen as `rtpe_now` in a timer thread is faked to be
exactly the time when the timer was supposed to run, and not the actual
current time, which means that a newly added packet can have a later
time stamp than the "now" the timer thread is using.

In some cases it's possible that some packets still arrive in userspace
immediately after a stream has been pushed to the kernel, for example if
some packets are already in the queue or if there is some processing
delay (e.g. writing to Redis). Allow for a short delay before counting a
stream as userspace if it has been pushed to the kernel.

Legacy UDP/TCP control protocols don't provide information about RTP
payload types, therefore don't pretend that we know that this is RTP.
Setting the RTP flag without knowing the payload types has the undesired
side effect that unknown payload types (all of them) would not be
handled by the kernel module.

If an offer is going to a side that is already known to support
rtcp-mux, don't try to offer a fallback RTCP port. Do this by pretending
that rtcp-mux=require is set, which leads to the correct behaviour. This
is needed because the RTCP fallback port might already be closed, so
trying to include it in the offer would require opening a new set of
ports, which is undesirable.

Zero SSRC are technically invalid, but the code accepts them as valid
and therefore sets up things like crypto contexts for zero SSRCs.
Consequently it's possible to have a zero SSRC first in the list of
SSRCs and other valid SSRCs later in the list, which means we can't use
the presence of a non-zero SSRC first in the list as a flag to determine
whether SSRC tracking is in use or not. Use an explicit flag instead.
