Subject: [PATCH] perf tools: Librarize trace_event() helper
Librarize trace_event() helper so that perf trace can use it too.
Also cleanup a bit the debug.h includes. It's not good to have it
included in perf.h because it doesn't make it flexible against other
headers it may need (headers that can also depend on perf.h and then
create a recursive header dependency).
