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`.

81ca479ca9 Python: local flow for type tracking 
summary flow is excluded from the local flow relation used for
typetracking, but included in the one used for global data flow.

0a589bed4e Python: Add inline test of MaD sinks 
This enables us to keep the framework modeling tests under `/frameworks`
folder

I had hoped to use `mad-sink[<kind>]` syntax, but that was not allowed
:(

Maybe it oculd be allowed in the future, but for now I'll stick with the
more ugly solution of `mad-sink__<kind>`
