for all operations. These are intended to future-proof the API a little by
making it easier to specify additional fields for without having to change
the API version for each.
At present, only two options are defined: one to explicitly specify
the device for an operation (rather than accepting the middleware's
autoselection) and another to specify the FIDO2 username that may
be used when generating a resident key. These new options may be
invoked at key generation time via ssh-keygen -O
This also implements a suggestion from Markus to avoid "int" in favour
of uint32_t for the algorithm argument in the API, to make implementation
of ssh-sk-client/helper a little easier.

Define some well-known error codes in the SK API and pass
them back via ssh-sk-helper.
Use the new "wrong PIN" error code to retry PIN prompting during
ssh-keygen of resident keys.

Allow passing a PIN via the SK API (API major crank) and let the
ssh-sk-helper API follow.
Also enhance the ssh-sk-helper API to support passing back an error
code instead of a complete reply. Will be used to signal "wrong PIN",
etc.

Adds a sk_load_resident_keys() function to the security key
API that accepts a security key provider and a PIN and returns
a list of keys.
Implement support for this in the usbhid middleware.

This extracts and refactors the client interface for ssh-sk-helper
from ssh-agent and generalises it for use by the other programs.
This means that most OpenSSH tools no longer need to link against
libfido2 or directly interact with /dev/uhid*

better match ec25519-sk keys. Discussed with markus@ and Sebastian Kinne
NB. if you are depending on security keys (already?) then make sure you
update both your clients and servers.

linking against the (previously external) USB HID middleware. The dlopen()
capability still exists for alternate middlewares, e.g. for Bluetooth, NFC
and test/debugging.

security key enrollment - these are possible for tokens that only offer self-
attestation. This also needs support from the middleware.
