ad49eada48 Python: Do not alter codeql-workspaces.yml 
And remove the qlpack referred to therein.
Instead we rename and duplicate the extesion file
that this qlpack pointed to.
These two extension files are kept in sync by `identical-files.json`.

9bd5694c3f Python: Add tests of path-graph for dataflow/taint-tracking 
Although this is actually using taint-tracking (so we can use the +=
statement), I would personally forget to check under the
dataflow/tainttracking folder to look for such a test, so I'm opting to
keep it under the dataflow/ folder.

dbc60140e0 Python: move tests to data extensions 
For these tests, we cannot use the same mechanism, as we want the
data extensions to be available for both tests.

Instead, we create a ql-pack for the test directory and point to
the data entensions from there. This makes the extensions
available for all tests in the directory.

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.
