<Sound Dev> [9] Review Request: 8167615 Opensource unit/regression tests for JavaSound

[Sergey Bylokhov]

Hello, Audio Guru.

Please review the fix for jdk9.

In the fix a number of tests are moved to the open ws. Note that most of 
the code moved as-is, and probably can be improved in the future, but I 
tried to limit the number of changes in this move.

Bug: https://bugs.openjdk.java.net/browse/JDK-8167615
Webrev can be found at: http://cr.openjdk.java.net/~serb/8167615/webrev.00
