perf script python: Add helpers for calling Python objects

Browse source

The Python script API repeatedly uses the same lines of code to get and
call objects.  Make that into helper functions instead.

A side-effect is that some reference counting bugs disappear because the
new call_object() function always decrements the reference count of
'retval'.
