/* Returns a SECStatus: SECSuccess or SECFailure, NOT SECWouldBlock. 
 * 
 * Currently, the list of functions called through ss->handshake is:
 *

 *  SocksStartGather
 *
 * In sslcon.c:
 *  ssl_GatherRecord1stHandshake

 *  ssl2_HandleVerifyMessage
 *  ssl2_BeginClientHandshake
 *  ssl2_BeginServerHandshake
 *  ssl2_HandleClientHelloMessage
 *  ssl2_HandleServerHelloMessage
 * 
 * The ss->handshake function returns SECWouldBlock under these conditions:
 * 1.	ssl_GatherRecord1stHandshake called ssl2_GatherData which read in 
 *	the beginning of an SSL v3 hello message and returned SECWouldBlock 
 *	to switch to SSL v3 handshake processing.
 *
 * 2.	ssl2_HandleClientHelloMessage discovered version 3.0 in the incoming
 *	v2 client hello msg, and called ssl3_HandleV2ClientHello which 
 *	returned SECWouldBlock.
 *
 * 3.   SECWouldBlock was returned by one of the callback functions, via
 *	one of these paths:
 * -	ssl2_HandleMessage() -> ssl2_HandleRequestCertificate() ->
 *	ss->getClientAuthData()
 *
 * -	ssl2_HandleServerHelloMessage() -> ss->handleBadCert()
 *
 * -	ssl_GatherRecord1stHandshake() -> ssl3_GatherCompleteHandshake() -> 
 *	ssl3_HandleRecord() -> ssl3_HandleHandshake() -> 
 *	ssl3_HandleHandshakeMessage() -> ssl3_HandleCertificate() -> 
 *	ss->handleBadCert()
 *
 * -	ssl_GatherRecord1stHandshake() -> ssl3_GatherCompleteHandshake() -> 
 *	ssl3_HandleRecord() -> ssl3_HandleHandshake() -> 
 *	ssl3_HandleHandshakeMessage() -> ssl3_HandleCertificateRequest() -> 
 *	ss->getClientAuthData()
 *
 * Called from: SSL_ForceHandshake	(below), 
 *              ssl_SecureRecv 		(below) and
 *              ssl_SecureSend		(below)
