d5e9f36747 Python: Add "enclosing callable" for ModuleVariableNode 
I've named this `DataFlowModuleScope` since it's not really a
callable (and all of the relevant methods are empty anyway).

3727c48227 Python: Record test changes 
Some of the places where flow has disappeared look a bit suspect, so I
don't consider this to be the final word on these tests.

e0f5b208da Python: Fix broken test of global typetracker flow 
The missing `global g` annotation meant `g = x` was interpreted as a
local assignment.

ab8cc23ce7 Python: Expand on taint sanitizer tests 
Most interesting to look at the custom sanitizers. Once we have use-use flow, we
should handle this case:

```
s = TAINTED_STRING
emulated_authentication_check(s)
ensure_not_tainted(s)
```

cf57afd102 Python: Add example of strange DataFlow::jumpStep 
The example code is just copied from command injection tests, that is not too
important. The important part is that `jumpStep` says there is flow from the
import of `os` to `app.route()` :O
