Currently there are no trace-cmd related plugins, all of them
are designed to be used with libtraceeevnt. As both libtraceevent
and trace-cmd have logic for managing plugins, the one in trace-cmd
is redundant. Those redundant code is removed and replaced with calls
to libtraceeevnt plugin APIs. When trace-cmd has to load any plugins,
it uses libtraceeevnt to do the job.

All existing plugins are moved from plugins/ to plugins/traceevent/
directory, as all of them (except plugin_python) are designed to be
used with the traceevent library. This change paves the way for
implementing trace-cmd specific plugins.

Tzvetomir  Stoyanov (VMware) (1):
  trace-cmd: Remove trace-cmd plugin handling routines

Tzvetomir Stoyanov (1):
  trace-cmd: Change plugin install directories

Tzvetomir Stoyanov (VMware) (4):
  trace-cmd: Move kernel_stack event handler to "function" plugin.
  trace-cmd: Move plugin options from trace-cmd to libtraceevent.
  trace-cmd: Move libtraceevent plugins in its own directory.
  trace-cmd: Load libtraceevent plugins from build folder, if exists.
