    perf: Have perf use the new libtraceevent.a library · aaf045f7
    Steven Rostedt authored
    The event parsing code in perf was originally copied from trace-cmd
    but never was kept up-to-date with the changes that was done there.
    The trace-cmd libtraceevent.a code is much more mature than what is
    currently in perf.
    
    This updates the code to use wrappers to handle the calls to the
    new event parsing code. The new code requires a handle to be pass
    around, which removes the global event variables and allows
    more than one event structure to be read from different files
    (and different machines).
    
    But perf still has the old global events and the code throughout
    perf does not yet have a nice way to pass around a handle.
    A global 'pevent' has been made for perf and the old calls have
    been created as wrappers to the new event parsing code that uses
    the global pevent.
    
    With this change, perf can later incorporate the pevent handle into
    the perf structures and allow more than one file to be read and
    compared, that contains different events.
