- NsfProcStubDeleteProc(): Protect against potentially dangling namespace references from within ::nsf::procs::*. The wrapper cmd's namespace of an nsf::proc might already have been deleted when ::nsf::procs::* shuts down finally. This showed up during a Tcl_Exit (NSF's ExitHandler) as an invalid memory access via (dangling) namespace pointers (valgrind).
- add new command nsf::parseargs to parse an argument vector against a parameter definition and to set the resulting variables in the current scope - extend regression test
