nsf.c:
- checked, that all CallDirectly() cases, where method is dispatched
  (no direct call) are covered by the regression tests
- avoid double memcpy() in dispatch recreate by using ObjectDispatch()
  rather than CallMethod()
- removed memcopy() in call-directy for "create"
- some more cleanup
genttclAPI.tcl:
- added option "-flags", which can be used for every parameter.
  example: .... -flags NSF_ARG_NOLEADINGDASH ....
- experimental: use NSF_ARG_NOLEADINGDASH for pattern "info subclass"
  to improve error messages.
