Re-initialize hostapd/wpa_supplicant git repository based on 0.6.3 release

/*
Convert TLS wrapper to use struct wpabuf This converts tls_connection_handshake(), tls_connection_server_handshake(), tls_connection_encrypt(), and tls_connection_decrypt() to use struct wpa_buf to allow higher layer code to be cleaned up with consistent struct wpabuf use.
