Subject: perf tools: Re-implement debug print function for linking
 python/perf.so

The python/perf.so python binding links a subset of objects.

Re-implement 'verbose' and 'eprintf' so they (and consequently
'pr_debug') can be used in objects linked into pythin/perf.so.

Note 'eprintf' must be re-implemented because the full version links the
browser ui.
