allowed_signers line that contains a namespace restriction, but no
restriction specified on the command-line; report and fix from Fabian Stelzer

matching of principals names against an allowed signers file.
Requested by and mostly written by Fabian Stelzer, towards a TOFU
model for SSH signatures in git. Some tweaks by me.

when using ca certs but not with simple key lifetimes within the allowed
signers file.
Since it returns the first keys principal it finds this could
result in a principal with an expired key even though a valid
one is just below.

NULLing the returned string. OpenBSD's getline handles this just fine, but
some implementations used by -portable do not. ok djm@

FIDO2 supports a notion of "user verification" where the user is
required to demonstrate their identity to the token before particular
operations (e.g. signing). Typically this is done by authenticating
themselves using a PIN that has been set on the token.
This adds support for generating and using user verified keys where
the verification happens via PIN (other options might be added in the
future, but none are in common use now). Practically, this adds
another key generation option "verify-required" that yields a key that
requires a PIN before each authentication.

from Markus:
use "principals" instead of principal, as allowed_signers lines may list
multiple.
When the signing key is a certificate, emit only principals that match
the certificate principal list.
NB. the command -Y name changes: "find-principal" => "find-principals"

This is populated during signature verification with additional fields
that are present in and covered by the signature. At the moment, it is
only used to record security key-specific options, especially the flags
field.

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.

for OpenSSH
This adds a simple manual signature scheme to OpenSSH.
Signatures can be made and verified using ssh-keygen -Y sign|verify
Signatures embed the key used to make them. At verification time, this
is matched via principal name against an authorized_keys-like list
of allowed signers.
