J.C. Jones a51561a1c4 Bug 1260318 - Scope U2F Soft Tokens to a single AppID r=qdot,rbarnes
This change includes the FIDO "App ID" as part of the function used to generate
the wrapping key used in the NSS-based U2F soft token, cryptographically binding
the "Key Handle" to the site that Key Handle is intended for.

This is a breaking change with existing registered U2F keys, but since our soft
token is hidden behind a pref, it does not attempt to be backward-compatible.

- Updated for rbarnes' and qdot's reviews comments. Thanks!
- Made more strict in size restrictions, and added a version field
  to help us be this strict.
- Bugfix for an early unprotected buffer use (Thanks again rbarnes!)
- Fix a sneaky memory leak re: CryptoBuffer.ToSECItem
