In some cases, that gets more accurate timing meaurements faster.

VLC does not use pa_stream_get_time(), so there is certainly no need
for pa_stream_get_time() to return monotonic values.

Such a latency update is an opportunity to reschedule the stream
trigger time, or to trigger immediately if late. That can reduce the
initial audio delay in some cases.

Also remove unchecked memory allocation.

-O3 enables dangerous optimizations and does not make much sense for a
protocol (not decoding => not performance critical) library.

The code is far from being great, but it matches the Qt intf now.

Fix #1859 #6983

Depending on the system, this can be called ducking, focus, policy...
But it basically boils down to pausing playback automatically when a
higher priority audio stream starts, typically a voice call.

Resuming playback automatically when communications are over would be
possible as well. But that seems unfriendly to me, so I skipped it.

This was not tested due to lack of hardware.

This reverts commit 12627b88.
