This commit adds a
rustls_supported_ciphersuite_protocol_version()
fn for getting the IANA registered protocol version identifier supported by a givenrustls_supported_ciphersuite
. This avoids downstream users having to userustls_supported_ciphersuite_get_name()
and then matching on the protocol version prefix in that identifier (e.g. curl/curl#14840). This is equivalent to the upstreamSupportedCipherSuite.version()
fn, but tailored to FFI users.
