Fixed STP_TRANSPORT_VERSION 1 behavior.
* runtime/transport/control.c (_stp_ctl_write_dbug): Added support for
more messages.
* runtime/transport/relay_v2.c (_stp_transport_data_fs_start): New
function.
(_stp_transport_data_fs_stop): Ditto.
(_stp_transport_data_fs_close): Moved some functionality into
_stp_transport_data_fs_stop() and calls _stp_transport_data_fs_stop()
also.
(_stp_transport_data_fs_init): Moved some functionality into
_stp_transport_data_fs_start() and calls _stp_transport_data_fs_start()
also.
* runtime/transport/relayfs.c (_stp_transport_data_fs_start): New
function.
(_stp_transport_data_fs_stop): Ditto.
(_stp_transport_data_fs_close): Moved some functionality into
_stp_transport_data_fs_stop() and calls _stp_transport_data_fs_stop()
also.
(_stp_transport_data_fs_init): Moved some functionality into
_stp_transport_data_fs_start() and calls _stp_transport_data_fs_start()
also.
* runtime/transport/ring_buffer.c (_stp_transport_data_fs_start): New
empty function.
(_stp_transport_data_fs_stop): Ditto.
* runtime/transport/transport.h: Added _stp_transport_data_fs_start() and
_stp_transport_data_fs_stop() prototypes.
* runtime/transport/transport.c (_stp_cleanup_and_exit): Calls
_stp_transport_data_fs_stop().
(_stp_transport_close): Calls _stp_transport_fs_close() earlier.
(_stp_transport_init): Calls _stp_transport_data_fs_start().
