perf scripting python: Extend interface to export data in a database-friendly way

Use the new db_export facility to export data in a database-friendly
way.

A Python script selects the db_export mode by setting a global variable
'perf_db_export_mode' to True.  The script then optionally implements
functions to receive table rows.  The functions are:

evsel_table
machine_table
thread_table
comm_table
dso_table
symbol_table
sample_table

An example script is provided in a subsequent patch.
