0778d90ac1 python: fix implementation of lambdaCreation
- still identifying summarized callables by name.
I think ther shoudl perhaps be a `getAUse` next to `getACall`.
- also fix tests, adding a standard taint configuration

f67be52b99 python: fix compilation
by making client code use the "new" class.
Really, this part of the split class should have the old name,
to minimise disruptions to clients.
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`.
