<Sound Dev> Sound-related types that are candidates to be FunctionalInterfaces in JDK 8

[Joe Darcy]

Hello,

As part of Project Lambda, a FunctionalInterface annotation type was 
added to the platform to mark interfaces that are intended to be used in 
lambda expressions.  I've sent out a code review request to add this 
annotation to types in the core-libs area [1].

To assist the sound team in adding analogous annotations to your types, 
the list of candidate types in for sound-related classes in java.* and 
javax.* is given below.  I recommend sub-tasks of JDK-8005297 "Add 
FunctionalInterface support to the platform" be used to track the work 
of adding @FunctionalInterface annotations to sound types.

Thanks,

-Joe
