* The GTlsClientConnection "use-ssl3" property now falls back to TLS
1.0 if SSL 3.0 has been disabled, rather than just failing. Also,
we now use the gnutls %LATEST_RECORD_VERSION option by default (to
allow connecting to certain servers that were incorrectly patched
for the POODLE attack), but also make sure to remove that option
in the fallback ("use-ssl3") mode (to allow connecting to other
servers that are differently broken). (#738633, #740087, Dan
