perf: Store trace event name/id pairs in perf.data
The trace event name<->id mapping is dynamic for each kernel
compile. In order for perf.data to be useable outside the actual
system, we thus need to store a table of this mapping for later
use.
This patch adds this table to perf.data, and provides helper
functions for lookup up fields from this table.
To avoid mistakes, lookup-from-table is kept completely seprate
from lookup-from-local-debugfs.
