8143850: retrofit ArrayDeque to implement List

[Martin Buchholz]

Thanks, Alex.

This has been on my todo list for a long time and I'm more overcommitted
than ever.

The difficult part is designing of the interface, but then there are many
tests to write...

I sort of liked ArrayDeque.asList() because at least then the API surface
to be added is small.

ArrayDeque has changed a little between jdk8 and now.

Almost all the code could be shared with the List-implementing class - we
don't want to introduce (too much) duplication.
