show that we do not recognize the sanitisers.

2daa9577bb ruby/python: implement shared module 
ruby:
- create new shared file `SummaryTypeTracker.qll`
- move much logic into the module
- instantiate the module
- remove old logic, now provided by module

python:
- clone shared file
- instantiate module
- use (some of the) steps provided by the module

9cb83fcdc9 python: add summaries for 
copy, pop, get, getitem, setdefault

Also add read steps to taint tracking.

Reading from a tainted collection can be done in two situations:
1. There is an acces path
    In this case a read step (possibly from a flow summary)
    gives rise to a taint step.
2. There is no access path
    In this case an explicit taint step (possibly via a flow
    summary) should exist.

c89b57997a Python: Change variable capture tests to use fresh variable names 
Instead of reusing `nonSink0` for both captureOut1NotCalled and
captureOut2NotCalled tests (I used 1/2 naming scheme to match things up
nicely).

I also added a comment highlighting that `m` is the function that is not
called (since I overlooked that initially :O)

also rename `collections.py` so it does not
clash with the standard library name.
This clash is an issue when testing locally.
