[PATCH]Users' Manual fixation about tbuf_size

Hi, All 

 This is users' manual fixation about tbuf_size
based on Xen 3.0.2 common/trace.c.
If this ML is wrong, please tell me appropriate ML. 

1)debug building is not needed for tracing buffer currently.
2)trace buffer default size is 0(trace.c line 35)

Your fix is correct; However, while you're in there, you might as well 
add a note about the 'setsize' command which is used to allocate the 
trace buffers, 'tbctl' which is used to dynamically enable tracing, and 
xenmon, which does both of those functions for you if they haven't 
already been done.
