alsa: use higher ports for listening
...
Allocate up to the first 16 ports, use the last 2 ports and free the
first 14 ports.
This ensure our ports are not among the first ports so that port 128
and following are for normal apps, what is usually expected when
PipeWire is not running.
Fixes #951

alsa-seq: remove the queue for system announce port
...
The announce messages are not put in a queue so we don't need
to allocate one (and a timer). Without the timer, we avoid wakeups
and consume less power.

node: we are supposed to produce data when != HAVE_DATA
...
We can produce data whenever the io area status != HAVE_DATA. We
don't need to look for NEED_DATA.
Also recycling buffer happens whenever the status != HAVE_DATA.

io: Add current video frame size to position
