Cleanup signature module before substantial change
There were some refinements applied while developing "Support Pointer Primitive Types by Arrays or Result Tuples". This patch moves these changes out which are not essential for that patch. They include - sort all mapping groups by name - replace huge regex by a pattern generator - replace dictionary string entries by SimpleNameSpace - improve PEP 563 handling - simplify "zero(sometype)" substantially - better handling of "QGenericMatrix" (preview) A test for the generated pattern against a reference parser was added. Task-number: PYSIDE-795 Task-number: PYSIDE-951 Change-Id: I5a6b236850c63a7db77b7f7b88881486fd1e61be Reviewed-by: Cristian Maureira-Fredes <cristian.maureira-fredes@qt.io>

+ of 4 at every level, as does the creation time. Up to a level of 6, this
