perf tools: Expose 'addr' functions so they can be reused
Move some functions and functionality related to the use of
'addr' out of builtin-script so they can be reused.
The moved functions are: is_bts_event() and sample_addr_correlates_sym()
and a new function perf_event__preprocess_sample_addr() is created from
bits of print_sample_addr().
perf_event__preprocess_sample_addr() is the equivalent of
perf_event__preprocess_sample() but for 'addr' instead of 'ip'.
