Import SSL_CTX_set_min_proto_version(3) from OpenSSL, suggested by jsing@.

While importing:
* Fix the prototypes, they all contained wrong datatypes.
* Delete SSL3_VERSION which is no longer supported.
* Delete TLS1_3_VERSION and DTLS1_2_VERSION, not yet supported.
* Delete the lie that these would be macros.
* Improve SEE ALSO and HISTORY sections.

+.Sh DESCRIPTION
+These functions set the minimum and maximum supported protocol
+versions for
+.Fa ctx
+or
+.Fa ssl .
+This works in combination with the options set via
+.Xr SSL_CTX_set_options 3
+that also make it possible to disable specific protocol versions.
+Use these functions instead of disabling specific protocol versions.
+.Pp
+Setting the minimum or maximum version to 0 will enable protocol
+versions down to the lowest or up to the highest version supported
+by the library, respectively.
+.Pp
+Currently supported versions are
+.Sy TLS1_VERSION ,
+.Sy TLS1_1_VERSION ,
+and
+.Sy TLS1_2_VERSION
+for TLS and
+.Sy DTLS1_VERSION
+for DTLS.
+.Sh RETURN VALUES
+These functions return 1 on success or 0 on failure.
+.Sh SEE ALSO
+.Xr ssl 3 ,
+.Xr SSL_CTX_new 3 ,
+.Xr SSL_CTX_set_options 3
+.Sh HISTORY
+These functions first appeared in OpenSSL 1.1.0
+and have been available since
+.Ox 6.2 .
