rather than being pointed to by the sslSocket. This reduces the number of malloc/free calls, and greatly reduces pointer fetches, and null pointer checks. sslGather and sslSecurityInfo are separately initialized. 2. SSL_ResetHandshake no longer deallocates and reallocates the sslSecurityInfo and all its subcomponents. 3. Many places that formerly did not check for memory allocation failures now do check, and do the right thing when allocation failed. git-svn-id: svn://10.0.0.236/trunk@115407 18797224-902f-48f8-a5cc-f745e15eee43
