tracing: Rename ftrace_event_buffer to trace_event_buffer.
The name "ftrace" really refers to the function hook infrastructure. It is not about the trace_events. The ftrace_event_buffer functions and data structures are for trace_events and not for function hooks. Rename them to trace_event_buffer*. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
