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 MozReview-Commit-ID: Jf6gNPauT4Y
