Some users want to disable SSL 3.0/TLS 1.0/TLS 1.1, and enable just TLS 1.2. In the future they might want to disable TLS 1.2 and enable just TLS 1.3, ... This commit makes it possible to disable any or all of the TLS or DTLS protocols. It also considerably simplifies the SSL/TLS tests, by auto-generating the min/max version tests based on the set of supported protocols (425 explicitly written out tests got replaced by two loops that generate all 425 tests if all protocols are enabled, fewer otherwise).
