* ext/openssl/ossl_ssl.c: support TLSv1.1 & TLSv1.1. Add

  SSLContext#version to inspect the version that was negotiated for
  a given connection.
* ext/openssl/extconf.rb: detect TLS 1.1 & 1.2 support.
* test/openssl/test_ssl.rb: add tests for TLS 1.1 & 1.2 given they
  are supported by the native OpenSSL being used.
