I had to rewrite the SINK1-SINK7 definitions, since this new requirement
complained that we had to add this `MISSING: flow` annotation :D
Doing this implementation also revealed that there was a bug, since I
did not compare files when checking for these `MISSING:` annotations. So
fixed that up in the implementation for inline taint tests as well.
(extra whitespace in argumentPassing.py to avoid changing line numbers
for other tests)
I went with NormalDataflowTest to signify that if you don't know what
you're looking for, this is probably the one. I did not want to just
call it DataflowTest, since that becomes a big vague when there are also
`FlowTest.qll` and `MaximalFlowTest.qll` -- I'm open to renaming this
though 👍
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.
