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.
