<Sound Dev> [9] Review Request: 8181566 JavaSound javadoc clarification

[Sergey Bylokhov]

Hello,
Please review the documentation fix for jdk9.
In the previous fixes the javadoc for javasound was cleared, but there are some small window for improvements.
I suggest to check the specdiff first, because for some methods the specification was reworked.

Bug: https://bugs.openjdk.java.net/browse/JDK-8181566
Specdiff: http://cr.openjdk.java.net/~serb/8181566/specdiff.00/overview-summary.html
Webrev can be found at: http://cr.openjdk.java.net/~serb/8181566/webrev.00


Common issues:
 - equals(),hashCode() have unusual description like "Finalizes the hashcode method"
 - Some classes like "Type" in "CompoundControl.java" has a notion about static instances, while there are no such instances(I assume this sentence a copied from other classes like from "Type" in BooleanControl.java).
 - In previous cleanup some classes and fields were not marked via {@code } tag.
 - In [1] Jonathan pointed to the documentation of html5 when the </p> is optional. I applied the similar existed html5 rule [2] for other tags </li>,</tr>,</td> - since we have no complicated tables/lists/layouts this stuff became smaller.
 - In some cases I updated the private specs as well, because I have an idea to enable (someday) doclint for private fields/methods in public packages.

ccc will be filed after technical review.
