Defender Extension Methods -- Resolution and Invoccation

[Paulo Levi]

Finally the old interfaces can be updated without breaking existing code.

If you don't mind i'd like to ask about the possible uses of this in the
platform today.
I have two that have irritated me, should be fairly common.

CharSequence missing getChars - supposed readonly interface requires reading
one by one when transfering to char[]
A classic: List.sort.

What are the methods you'd like to add a default implementation of to what
interfaces (in the expectation ofourse that implementations would provide
better defaults).
