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.

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.

Don't call OpenSSL_add_all_algorithms() unless OpenSSL actually
supports it.
Move all libcrypto initialisation to a single function, and call that
from seed_rng() that is called early in each tool's main().

Disables and removes dependency on OpenSSL. Many features don't
work and the set of crypto options is greatly restricted. This
will only work on system with native arc4random or /dev/urandom.
Considered highly experimental for now.
deprecate key_load_private_pem() and
sshkey_load_private_pem() interfaces. Refactor the generic key loading API to
not require pathnames to be specified (they weren't really used).
Fixes a few other things en passant:
Makes ed25519 keys work for hostbased authentication (ssh-keysign
previously used the PEM-only routines).
Fixes key comment regression bz#2306: key pathnames were being lost as
comment fields.

Add FingerprintHash option to control algorithm used for
key fingerprints. Default changes from MD5 to SHA256 and format from hex to
base64.

Tweak config reparsing with host canonicalisation
Make the second pass through the config files always run when
hostname canonicalisation is enabled.
Add a "Match canonical" criteria that allows ssh_config Match
blocks to trigger only in the second config pass.
Add a -G option to ssh that causes it to parse its configuration
and dump the result to stdout, similar to "sshd -T"
Allow ssh_config Port options set in the second config parse
phase to be applied (they were being ignored).

unnecessary arc4random_stir() calls. The only ones left are to ensure
that the PRNG gets a different state after fork() for platforms that
have broken the API.
