* Restconf authentication callback (ca_auth) signature changed

* Not backward compatible: All uses of the ca-auth callback in restconf plugins must be changed
  * New version is: `int ca_auth(h, req, auth_type, authp, userp)`
    * where `auth_type` is the requested authentication-type (none, client-cert or user-defined)
    * `authp` is the returned authentication flag
    * `userp` is the returned associated authenticated user
    * and the return value is three-valued: -1: Error, 0: ignored, 1: OK
  * For more info see [clixon-docs](https://clixon-docs.readthedocs.io/en/latest/restconf.html)
* New clixon-restconf@2020-12-30.yang revision
