gentclAPI.tcl: - handle duplicated domains by folding these to a single definition
nsf.c:
- added command nsf::method::get.
Rationale: provide a central place to obtain information
about all kind of method handles, which might be
- scripted and c-based methods
- nsf::procs
- plain tcl procs
- cmds (with and without paramter definitions)
- make results of ListMethod() robust against missing
information (e.g. plain tcl cmds, missing object registrations,
etc.)
- factor out common code for ListMethod call sites
for per-object methods, instance methods and procs/cmds
to ListMethodResolve()
- return errors from failing converter registrations
- extend regression test (new test set nsf-method.test)
