This patch implements the W3C Web Authentication API from
https://www.w3.org/TR/webauthn/, currently the 28 September 2016
working draft.
It utilizes a tentative binding of the U2F NSS Soft Token to provide
authentication services while waiting on Bug 1245527 to support USB HID-based
U2F tokens. This binding is not in the specification yet, so it should be
considered an experiment to help the specification move fowrard.
There are also a handful of deviations from the specification's WebIDL, which
are annotated with comments in WebAuthentication.webidl.
There are no tests in this commit; they are in Part 4 of this commit series.
There is a small script online at https://webauthn.bin.coffee/ to exercise this
code, but it doesn't do any automated checks.
There are also a handful of TODOS:
1) The algorithm to relax the same-origin restriction is in Part 3.
2) The use of AlgorithmIdentifier and having a way to coerce an object to a
string is still missing.
3) Timeouts and deadlines aren't there, and are pending reworking how
the nsIU2FToken interface works.
