The function graph tracer is called just "function_graph" (no trailing
"_tracer" needed).

- fix some typos
- document the difference between '>' and '>>'
- document the 'enable' toggle
- remove section "Defining an event-enabled tracepoint", since it's
out-dated and sample/trace_events/ already serves this purpose.
v2: add "Updated by Li Zefan"
[ Impact: make documentation up-to-date ]

Fix typo about chart to map the kernel priority to user land priorities.
* About sched_setscheduler(2)
Processes scheduled under SCHED_FIFO or SCHED_RR
can have a (user-space) static priority in the range 1 to 99.
(reference: http://www.kernel.org/doc/man-pages/online/pages/
man2/sched_setscheduler.2.html)
* From: Steven Rostedt
0 to 98 - maps to RT tasks 99 to 1 (SCHED_RR or SCHED_FIFO)
99 - maps to internal kernel threads that want to be lower than RT tasks
but higher than SCHED_OTHER tasks. Although I'm not sure if any
kernel thread actually uses this. I'm not even sure how this can be
set, because the internal sched_setscheduler function does not allow
for it.
100 to 139 - maps nice levels -20 to 19. These are not set via
sched_setscheduler, but are set via the nice system call.
140 - reserved for idle tasks.

Move kmemtrace.txt, tracepoints.txt, ftrace.txt and mmiotrace.txt to
the new trace/ directory.
I didnt find any references to those documents in both source
files and documents, so no extra work needs to be done.
