* procfs.c (_stp_proc_write_cmd): Check return code for
_stp_transport_open().
* transport.c (_stp_transport_write): This function
can now sleep because it is
(_stp_handle_start): Don't use a mutex when a simple atomic
will do.
(_stp_work_queue): Check atomic to see if probe_start()
has finished before attempting exit.
(_stp_transport_close): PR2391. Cancel work queue.
(_stp_transport_init): If _stp_register_procfs() fails,
return an error code.
* transport.txt: New file. Documents transport initialization and
shutdown sequence.
