Merge Add PivotRootRule class

Browse Source 
... and tests for it.

This replaces the old code that just stores the full rule as text.

We also get rid of the old ['allow'] and ['deny'] items in
ProfileStorage, the handling of old write functions, and the last usage
of _Raw_Rule (and therefore _Raw_Rule itsself).

Also delete the old test-pivot_root_parse.py which relied on the ancient
code, and even used a wrong syntax in its test rules.

Oh, and aa-logprof can now ask about pivot_root events.

See the individual commits for details.
