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.

ce4b192caa Python: Improve usefulness of RemoteFlowSourcesReach meta query
Before, results from `dca` would look something like

    ## + py/meta/alerts/remote-flow-sources-reach

    - django/django@c2250cf_cb8f: tests/messages_tests/urls.py:38:16:38:48
        reachable with taint-tracking from RemoteFlowSource
    - django/django@c2250cf_cb8f: tests/messages_tests/urls.py:38:9:38:12
        reachable with taint-tracking from RemoteFlowSource

now it should make it easier to spot _what_ it is that actually changed,
since we pretty-print the node.

6591a86aad Python: Add test cases
I debated whether to add a
`MISSING: use=moduleImport("builtins").getMember("print").getReturn()`
annotation to the last line.

Ultimately, I decided to add it, as we likely _do_ want this information
to propagate into inner functions (even if the value of `var2` may
change before `func4` is called).

233ae5a54b Python: Fix FP in py/unused-local-variable
This is only a temporary fix, as indicated by the TODO comment.

The real underlying issue is the fact that `isUnused` is defined in
terms of the underlying SSA variables (as these are only created
for variables that are actually used), and the fact that annotated
assignments are always considered to redefine their targets, which may
not actually be the case.

Thus, the correct fix would be to change the extractor to _disregard_
mere type annotations for the purposes of figuring out whether an
SSA variable should be created or not.

However, in the short term the present fix is likely sufficient.

8b3fa789da Python: Add AnnAssign DefinitionNode
This was a source of false positives for the

case.
