Add load_hostkeys_file() and hostkeys_foreach_file() that accept a
FILE* argument instead of opening the file directly.
Original load_hostkeys() and hostkeys_foreach() are implemented using
these new interfaces.
Add a u_int note field to the hostkey_entry and hostkey_foreach_line
structs that is passed directly from the load_hostkeys() and
hostkeys_foreach() call. This is a lightweight way to annotate results
between different invocations of load_hostkeys().

When we know that a particular action will require a PIN, such as
downloading resident keys or generating a verify-required key, request
the PIN before attempting it.

When PINs are in use and multiple FIDO tokens are attached to a host, we
cannot just blast requests at all attached tokens with the PIN specified
as this will cause the per-token PIN failure counter to increment. If
this retry counter hits the token's limit (usually 3 attempts), then the
token will lock itself and render all (web and SSH) of its keys invalid.
We don't want this.
So this reworks the key selection logic for the specific case of
multiple keys being attached. When multiple keys are attached and the
operation requires a PIN, then the user must touch the key that they
wish to use first in order to identify it.
This may require multiple touches, but only if there are multiple keys
attached AND (usually) the operation requires a PIN. The usual case of a
single key attached should be unaffected.

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.

Allow writing to disk the attestation certificate that is generated by
the FIDO token at key enrollment time. These certificates may be used
by an out-of-band workflow to prove that a particular key is held in
trustworthy hardware.
Allow passing in a challenge that will be sent to the card during
key enrollment. These are needed to build an attestation workflow
that resists replay attacks.
