Generate short wrappers for "__await__()" special method to adapt its signature for the PyCFunction entry in PyMethodDef.
See #2363.

Generate short wrappers for special methods like "__next__()" to adapt their signature for the PyCFunction entry in PyMethodDef.
Previously, their cast to a two-argument PyCFunction was incorrect.
See #2363.

Ignore exact function pointer type in PyCFunction pointer comparison since there is no use in figuring out the correct cast here.

Reduce Cython's module size of "Actions", "Scanners", "StringIOTree", "Visitor" and "Code" by disabling auto-pickling.

Fix function signature casts in PyMethodDef structs that lead to warnings in gcc-8 (and actually make use of the warnings in gcc-8).
