libinterimap: deprecate SSL_protocols and introduce SSL_protocol_{min,max}.
Using the libssl interface simplifies our protocol black/whitelist greatly; this only allows simple min/max bounds, but holes are arguably not very useful here. Using the new settings bumps the required libssl version to 1.1.0.
