I'm not sure here: if we do the +1 adjustment we'd be consistent with
the value reported by getsockopt, but OTOH users may get confused
about seeing a value larger than TLS_MAX_PAYLOAD_SIZE.

Makes sense to keep the behaviour the same as getsockopt() right? So
add the +1 changes here based on version (same as getsockopt()). In
which case, it should never exceed TLS_MAX_PAYLOAD_SIZE.

The max value for 1.3 is TLS_MAX_PAYLOAD_SIZE+1 (after adjustment),
since it's the max value that will be accepted by setsockopt (after
passing the "value - 1 > TLS_MAX_PAYLOAD_SIZE" check). And it's the
value most users will see since it's the default.
