Description:- TLS cipher negociation happens incorrectly
leading to the use of a different

Analysis:- YaSSL based MySQL server will compare only the
last byte of each cipher sent in the Client Hello message.
This can cause TLS connections to fail, due to the server
picking a cipher which the client doesn't actually support.

Fix:- A fix for detecting cipher suites with non leading
zeros is included as YaSSL only supports cipher suites with
leading zeros.
