	* transport_msgs.h: ifdef old messages as such.
	Add support for new transport.
	* relayfs.c: Simplify and add new interface to look
	like utt.
	* utt.[ch]: New files. Similar to the proposed utt interface.
	These setup and teardown relayfs on debugfs.
	* control.c: New file. Implements a simple control channel.
	A small subset of procfs.c.
	* procfs.c: This is now only used for old kernels lacking newer
	relayfs. Change STP_RELAYFS to STP_BULKMODE. Use new
	messages from transport_msgs.h. Don't support
	RELAYFS_CHANNEL_VERSION >= 4. CHanges all control channel functions
	to new names. Use pids instead of module names in /proc names.
