* [pulseaudio] Removing isIdle test
The isIdle boolean was not properly handled.
When disconnection is called, isIdle is not relevant : we should always honnor the disconnection request.
In fact, isIdle prevented disconnection when it is necessary (example : when a IOException occurs when sending audio to sink)
+Little bug fix on volume parsing: some volume request doesn't respond with a space after the comma separating left/right channel.
* [pulseaudio] Enhancement to the idle detection for disconnection
Using a counter to count client instead of a isIdle variable, which was not thread safe.
The PulseaudioSimpleProtocolStream parent class is now the sole responsible for closing source or sink stream.
* [pulseaudio] Small performance enhancement
Avoid a costly synchronized operation for a method called very often.
