upstream: Refactor signing - use sshkey_sign for everything,
including the new U2F signatures. Don't use sshsk_ecdsa_sign() directly, instead make it reachable via sshkey_sign() like all other signature operations. This means that we need to add a provider argument to sshkey_sign(), so most of this change is mechanically adding that. Suggested by / ok markus@ OpenBSD-Commit-ID: d5193a03fcfa895085d91b2b83d984a9fde76c8c
