Upgrade to use authenticated web socket protocol

[timbl]

This needs to be done in conjunction with NSS being upgraded to allow (and check if sent) authentication information.

There is a question as to the extent that this should be negotiated between the parties or with time just required.

Yes!

Here is the relevant issue in the spec and a possible alignment .

Sounds like inrupt/solid-client-authn-js#538 is now a WONT_FIX.
So I'll wait for a few more weeks to see what happens, and if it seems clear that Inrupt's client will not support it, then we can always just add our own code for it (but still use Inrupt's client as much as possible).
