OpenSSL: don't disable security work-around
OpenSSL added a work-around for a SSL 3.0/TLS 1.0 CBC vulnerability (http://www.openssl.org/~bodo/tls-cbc.txt). In 0.9.6e they added a bit to SSL_OP_ALL that _disables_ that work-around despite the fact that SSL_OP_ALL is documented to do "rather harmless" workarounds. The libcurl code uses the SSL_OP_ALL define and thus logically always disables the OpenSSL fix. In order to keep the secure work-around workding, the SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS bit must not be set and this change makes sure of this. Reported by: product-security at Apple
