java.io.Closeable and BindingProvider

[Tomas-Kraus]

It is desirable to have client objects(dispatch and proxy) support java.io.Closeable.

1. BindingProvider extends java.io.Closeable. This is straightforward but a API change.

2. No API change, but in JAX-WS spec add a statement that client objects(dispatch and proxy) may/should/must implement the java.io.Closeable.
