* src/java/org/classpath/icedtea/pulseaudio/PulseAudioDataLine.java
Fixed code formatting.
(open): Changed modifier from public to protected. PulseAudioClip wont
expose this meaningless (for a Clip) function.
(createStream): Changed modifier from public to private. Dont want this
function exposed.
(addStreamListeners): Likewise.
(connect): Likewise.
(open): Changed modifier from public to proected. Dont want this method
exposed for all subclasses of PulseAudioDataLine.
* src/java/org/classpath/icedtea/pulseaudio/PulseAudioLine.java
(open): Removed redundant method.
* src/java/org/classpath/icedtea/pulseaudio/PulseAudioSourceDataLine.java
(open): New function. Implements a required function for SourceDataLine
interface. Previous implementation was through DataLine.open which was
made protected.
* src/java/org/classpath/icedtea/pulseaudio/PulseAudioTargetDataLine.java
(open): New function. Implements a required function for TargetDataLine
interface. Previous implementation was through DataLine.open which was
made protected.
(connectLine): Change modifier to protected.
