This avoids the need to initialize libtraceevent, plugins, etc. It is sufficient for many tracepoint commands to work like: $ perf stat -e sched:sched_switch true To populate evsel->tp_format, do lazy initialization using libtraceevent in the evsel__tp_format function (the sys and name are saved in evsel__newtp_idx for this purpose). Reading the id should be indicative of the format failing to load, but if not an error is reported in evsel__tp_format. This could happen for a tracepoint with a format that fails to parse. As tracepoints can be parsed without libtraceevent with this, remove the associated #ifdefs in parse-events.c. By only lazily parsing the tracepoint format information it is hoped this will help improve the performance of code using tracepoints but not the format information. It also cuts down on the build and ifdef logic.

Remove the Build logic and #ifdefs that caused the tests not to be run. Test code that directly uses libtraceevent is still guarded.
