RFR: 8023275: Wrapping collections should override default methods

[Henry Jen]

Hi,

Please review the webrev at
http://cr.openjdk.java.net/~henryjen/tl/8023275/0/webrev/

The patch adds override on default methods for a couple wrapping classed
and delegate those to underlying class.

There is a minor revise on synchronizedCollection javadoc to cover Stream.

A sanity check on wrapper classes to ensure default methods are override.

Those changes has been in lambda repo since long ago.

Cheers,
Henry
