perf scripts python: export-to-sqlite.py: Export switch events
Export switch events to a new table 'context_switches' and create a view
'context_switches_view'. The table and view will show automatically in
the exported-sql-viewer.py script.
If the table ends up empty, then it and the view are dropped.
Committer testing:
Use the exported-sql-viewer.py and look at "Tables" ->
"context_switches":
id machine_id time cpu thread_out_id comm_out_id thread_in_id comm_in_id flags
1 1 187836111885918 7 1 1 2 2 3
2 1 187836111889369 7 1 1 2 2 0
