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.

This change stops including the old packet_* API by default and makes

Use consistent format in debug log for keys readied, offered and
received during public key authentication.
This makes it a little easier to see what is going on, as each message
now contains (where available) the key filename, its type and fingerprint,
and whether the key is hosted in an agent or a token.

wildcard.
Algorithm lists are now fully expanded when the server/client configs
are finalised, so errors are reported early and the config dumps
(e.g. "ssh -G ...") now list the actual algorithms selected.
Clarify that, while wildcards are accepted in algorithm lists, they
aren't full pattern-lists that support negation.
