tracer: parser: small speedup
...
Add a parser_perf test. Skip the extra filter stage and change the regex to
match on category=TRACE lines only.
Also flip the check in analysis_runner, since we only have a few tracer
classes in the beginning, the rest are tracer entries.

tracer: add new python library to process tracer logs

This is the beginning of a python library for wrting tools that process tracer
logs. This library contains a structure parser written in python to avoid the
dependency on gobject introspection (and the slowness and non pythoness that
comes with it).
