This is currently semi-works -- the import is allowed, but doesn't
always work when used :|

044829c3bb Python: Add @security-severity to py/pam-auth-bypass 
The value 8.1 was calculated by our internal tool. This corresponds to a
'High' severity, which from my gut feeling seems reasonable for
authorization bypass.

Really, this part of the split class should have the old name,

Same goes for the other split classes.

f14ee0e794 python: Flow summaries based on type tracking 
Two classes have been inserted into the hierarchies:

- `NonLibraryDataFlowCallable` with a method `getACall2`.
This method implements "get a call, not considering flow summaries".
For `NonLibraryDataFlowCallable`s, `getACall` will defer to `getACall2`.
While you could have a synthesised call to such a callable,
it would not correspond to a `CallNode`.

- `NonLibraryDataFlowSourceCall` with methods
`getArg2` and `getCallable2`. These also refer to a call graph that
does not consider flow summaries.

`getArg2` is used to synthesise pre-update nodes for arguments.

`getCallable2` is used in `connects` to compute argument passing.
This is used to define data flow nodes for overflow arguments.

`getACall2` ensures that `LibraryCallableValue::getACall` is not called
when the charpred of `FunctionCall` is evaluated.

506efcf051 python: refactor TDataFlowCall 
- Branch predicates are made simple. In particular, they do not try to detect library calls.
- All branches based on `CallNode`s are gathered into one.
- That branch has been given a class `NonSpecialCall`, which is the new parent of call classes based on `CallNode`s. (Those classes now have more involved charpreds.)
- A new such class, 'LambdaCall` has been split out from `FunctionCall` to allow the latter to replace its
  general `CallNode` field with a specific `FunctionValue` one.
- `NonSpecialCall` is not an abstract class, but it has some abstract overrides. Therefor, it is not
  considered a resolved call in the test `UnresolvedCalls.qll`.
