pulse-server: add a pulse.idle.timeout option

Browse source 
When a client is not sending any data when it should be and causes an
underrun, mark it as idle and record the timestamp.

When a client is idle for pulse.idle.timeout seconds, set the stream
as inactive. When more data is received, set it back to active.

Add a pulse.idle.timeout option to set a global server default or
a per-stream value. Set the server default to 5 seconds. A value of 0
can be used to disable this feature.

With this change, badly behaving clients that are not sending any data
will be paused so that the sinks can suspend to save battery power.

Fixes #2839
