5bff5188ac Python: switch from negative to positive list 
This should avoid potentially terrible performance.
Also noted the missing syntactic constructs,
as I went through the documnetation.

e865a290de Python: straight port of query 
The old query uses `pointsTo` to limit the sinks
to methods on lists and dictionaries.
That constraint is omitted here which could hurt performance.

af91a2df00 Python: Prevent explosion in poly-ReDoS query 
I consider this to be a short-term solution to the performance problems
we identified. The choice of "at most ten occurrences of `.*`" is
somewhat arbitrary, and it's possible a higher limit would work just as
well.

badf6311c9 Python: Remove flow between globals... 
... in a local scope. Or rather, remove these from the `hasLocalSource`
relation.

This prevents a quadratic blowup when the same global is mentioned
_a lot_ of times within a single function scope.

ed794f42b5 Python: Soft revert TypeTrackingNode 
Temporarily instates `TypeTrackingNode` as an alias of `LocalSourceNode`
as having it as a separate class lead to performance regressions.

In the hopes that this will be resolved in the near future, I have left
the current `TypeTrackingNode` implementation in situ, but hidden inside
a `FutureWork` private module.
