A static null-coalescing method

[Roger Riggs]

Hi,

I guess I'd stop slacking off and figure out where that method goes.
It's not clear it belongs on Optional, since it doesn't produce or 
consume an Optional.
java.util.Objects is seems better as long as it can be named to avoid 
any confusion with other methods.
