These patches implement a tool that can be used to read and write the
sysfs files, with subcommands!

The following subcommands are implemented:
	rpcsys rpc-client
 	rpcsys xprt
 	rpcsys xprt set
 	rpcsys xprt-switch
 	rpcsys xprt-switch set

So you can print out information about every xprt-switch with:
	anna@client ~ % rpcsys xprt-switch
	switch 0: num_xprts 1, num_active 1, queue_len 0
		xprt 0: local, /var/run/gssproxy.sock [main]
	switch 1: num_xprts 1, num_active 1, queue_len 0
		xprt 1: local, /var/run/rpcbind.sock [main]
	switch 2: num_xprts 1, num_active 1, queue_len 0
		xprt 2: tcp, 192.168.111.1 [main]
	switch 3: num_xprts 4, num_active 4, queue_len 0
		xprt 3: tcp, 192.168.111.188 [main]
		xprt 4: tcp, 192.168.111.188
		xprt 5: tcp, 192.168.111.188
		xprt 6: tcp, 192.168.111.188

And information about each xprt:
	anna@client ~ % rpcsys xprt
	xprt 0: local, /var/run/gssproxy.sock, port 0, state <MAIN,CONNECTED,BOUND>
		Source: (einval), port 0, Requests: 2
		Congestion: cur 0, win 256, Slots: min 2, max 65536
		Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0
	xprt 1: local, /var/run/rpcbind.sock, port 0, state <MAIN,CONNECTED,BOUND>
		Source: (einval), port 0, Requests: 2
		Congestion: cur 0, win 256, Slots: min 2, max 65536
		Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0
	xprt 2: tcp, 192.168.111.1, port 2049, state <MAIN,CONNECTED,BOUND>
		Source: 192.168.111.222, port 959, Requests: 2
		Congestion: cur 0, win 256, Slots: min 2, max 65536
		Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0
	xprt 3: tcp, 192.168.111.188, port 2049, state <MAIN,CONNECTED,BOUND>
		Source: 192.168.111.222, port 921, Requests: 2
		Congestion: cur 0, win 256, Slots: min 2, max 65536
		Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0
	xprt 4: tcp, 192.168.111.188, port 2049, state <CONNECTED,BOUND>
		Source: 192.168.111.222, port 726, Requests: 2
		Congestion: cur 0, win 256, Slots: min 2, max 65536
		Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0
	xprt 5: tcp, 192.168.111.188, port 2049, state <CONNECTED,BOUND>
		Source: 192.168.111.222, port 671, Requests: 2
		Congestion: cur 0, win 256, Slots: min 2, max 65536
		Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0
	xprt 6: tcp, 192.168.111.188, port 2049, state <CONNECTED,BOUND>
		Source: 192.168.111.222, port 934, Requests: 2
		Congestion: cur 0, win 256, Slots: min 2, max 65536
		Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0

You can use the `set` subcommand to change the dstaddr of individual xprts:
	anna@client ~ % sudo rpcsys xprt --id 4 
	xprt 4: tcp, 192.168.111.188, port 2049, state <CONNECTED,BOUND>
		Source: 192.168.111.222, port 726, Requests: 2
		Congestion: cur 0, win 256, Slots: min 2, max 65536
		Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0
	anna@client ~ % sudo rpcsys xprt set --id 4 --dstaddr server2.nowheycreamery.com
	xprt 4: tcp, 192.168.111.186, port 2049, state <CONNECTED,BOUND>
		Source: 192.168.111.222, port 726, Requests: 2
		Congestion: cur 0, win 256, Slots: min 2, max 65536
		Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0

Or for changing the dstaddr of all xprts attached to a switch:
	anna@client % rpcsys xprt-switch --id 3
	switch 3: num_xprts 4, num_active 4, queue_len 0
		xprt 3: tcp, 192.168.111.188 [main]
		xprt 4: tcp, 192.168.111.188
		xprt 5: tcp, 192.168.111.188
		xprt 6: tcp, 192.168.111.188
	anna@client % sudo rpcsys xprt-switch set --id 4 --dstaddr server2.nowheycreamery.vm
	switch 3: num_xprts 4, num_active 4, queue_len 0
		xprt 2: tcp, 192.168.111.186 [main]
		xprt 3: tcp, 192.168.111.186
		xprt 5: tcp, 192.168.111.186
		xprt 6: tcp, 192.168.111.186


I renamed the tool to "rpcsys" after the discussion at the bakeathon. I
think this is at least a better name, but if anybody has other ideas
please let me know!

Thoughts?
