Subject: ssl: Add BEAST mitigation selection option

Some legacy TLS 1.0 software does not tolerate the 1/n-1 content
split BEAST mitigation technique. This commit adds a beast_mitigation
SSL option (defaulting to one_n_minus_one) to select or disable the
BEAST mitigation technique.

Valid option values are (one_n_minus_one | zero_n | disabled).
