Motivation: If the destination buffer is completely filled during a call to OpenSslEngine#wrap(..) we may return NEED_UNWRAP because there is no data pending in the SSL buffers. However during a handshake if the SSL buffers were just drained, and filled up the destination buffer it is possible OpenSSL may produce more data on the next call to SSL_write. This means we should keep trying to call SSL_write as long as the destination buffer is filled and only return NEED_UNWRAP when the destination buffer is not full and there is no data pending in OpenSSL's buffers. Modifications: - If the handshake produces data in OpenSslEngine#wrap(..) we should return NEED_WRAP if the destination buffer is completely filled Result: OpenSslEngine returns the correct handshake status from wrap().
