<Sound Dev> [10] Review Request: 8178401 Various audio files writers do not close file streams properly

[Sergey Bylokhov]

Hello, Audio Guru.
Please review the fix for jdk10.

Bug: https://bugs.openjdk.java.net/browse/JDK-8178401
Webrev can be found at: http://cr.openjdk.java.net/~serb/8178401/webrev.01

Description:
Most of our audio file writers can try to convert the saved audio stream 
to the format which is supported by the current writer, for example it 
can convert big<->little-endian, signed/unsigned, etc. Because of 
unsupported conversion (or because of some other reasons) we can get 
some exceptions. In this case we have to close all streams, because such 
streams can lock the file on Windows.

This particular bug is responsible for a grown number of temporary files 
on our automated test systems and causes some intermittent failures.
