f07a7bf8cf Python: Autoformat everything using qlformat.
Will need subsequent PRs fixing up test failures (due to deprecated
methods moving around), but other than that everything should be
straight-forward.

cac261858c Python: Don't report mutable parameters that are in fact immutable.
Fixes #1832.

In the taint sink, we add an additional check that the given control-flow node
can indeed point to a value that is mutable. This takes care of the guard on the
type.

If and when we get around to adding configurations for all of the taint
analyses, we may want to implement this as a barrier instead, pruning any steps
that go through a type test where the type is not mutable.
