[PATCH 06/10] perf python: Add perf.tracepoint method

[Jiri Olsa]

To get id of the tracepoint from subsystem and
name strings. The interface is:

  id = perf.tracepoint(sys, name)

In case of error -1 is returned.

It will be used to get python tracepoint event's
config value for tracepoint event.
