For HTTP public key pinning (RFC7469), the SHA-256 hash of the Subject
Public Key Info (which usually only changes when the public key
changes) is used rather than the SHA-1 hash of the entire certificate
(which will change on each certificate renewal).
ssl_set_hostname was mostly useless, because it allowed setting host name of an existing SSL object. However SNI was sent as part of client_hello, which was done in ssl_client_new. So it wasn't possible to actually set host name before connection would start.
