* src/java/org/classpath/icedtea/pulseaudio/PulseAudioTargetDataLine.java
New class variables flushed and drained.
(close): Now synchronized.
(open): Likewise.
(open): Likewise.
(read): Likewise. Return when flush()ed, drain()ed, stop()ed or close()d.
(drain): Synchronized. Sets drained to true.
(flush): Sets flushed to true.
(start): Synchronized.
(stop): Synchronized.
* unittests/org/classpath/icedtea/pulseaudio/PulseAudioTargetDataLineTest.java
(testReadAndDrain): Fixed test and made it active.
