[0/8] Cleanup traceevent API and make it more consistent

Message

Tzvetomir Stoyanov March 26, 2019, 3:43 p.m. UTC

This patch series does a cleanup of traceevent implementation and APIs:
 - All "pevent" function parameters and local variables are renamed to "tep". 
   This makes the implementation consistent with the chosen naming convention, 
   tep (trace event parser), and avoids any confusion with the old "pevent" name 
 - Removed deprecated tep filter trivial APIs.
 - Removed call to exit() from one of traceevent APIs, a library function should 
   not force the application to exit.
 - Added counter to track parsing failures.

Changes depend on "Few patches, related to libtracevent APIs" patchset and 
should be applied on top of it.
