pulse-server: add a pulse.zeroramp.gap property

Browse source 
Add a new pulse.zeroramp.gap property that will enable gap detection and
fade-in/fade-out on gaps on playback streams.

Make a rule to enable this on chrome, which does not do a cork/pause
when a stream is paused but sends out silence. With the gap detection
enabled, this allows the audioconvert to perform fades to avoid pops and
clocks from sudden DC changes at the gaps.

Fixes #4745
