Steven Rostedt 0e730bc067 tracing: Move __trace_buffer_{un}lock_*() functions to trace.h 
The file trace.c has become a catchall for most things tracing. Start
making it smaller by breaking out various aspects into their own files.

Move the __always_inline functions __trace_buffer_lock_reserve(),
__trace_buffer_unlock_commit() and trace_event_setup() into trace.h.

The trace.c file will be split up and these functions will be used in more
than one of these files. As they are already __always_inline they can
easily be moved into the trace.h header file.
