[v5,0/2] Remove redundant trace-cmd plugin handling logic

Message

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 lib/traceevent/plugins
directory, as all of them are designed to be used with the traceevent
library.

An initial infrastructure for trace-cmd specific plugins is added - 
new lib/trace-cmd/plugins directory and an initial set of APIs
for working with trace-cmd plugins.

[
  changes:
   - Removed accepted patches from the patch set.
   - Moved logic which loads traceevent development
     plugins from libtraceevent to trace-cmd application.
]

Tzvetomir Stoyanov (VMware) (2):
  trace-cmd: Load libtraceevent plugins from build folder, if exists.
  trace-cmd: Add initial infrastructure for trace-cmd specific plugins.
