nsf.c, gentclAPI.tcl: - new argument types "virtualobjectargs" and "virtualclassargs" for context-specific argument resolutions: when a context object is provided, arguments of type "virtualobjectargs" are determined based on the slots applicable for the object (like "... lookup ..."), arguments of type "virtualclassargs" are resolved against a class. These types are used as follows: /obj/ configure /virtualobjectargs/ /cls/ create /name/ /virtualclassargs/ /cls/ recreate /name/ /virtualclassargs/ /cls/ new ?-childof /obj/? /virtualclassargs/ This new feature allows us to provide better error messages and to make much of the "... info ... configure parameter ..." infrastructure much less important. - For "virtualclassargs" we need the functionality to obtain from the C-Code based on a class the configure parameters applicable to objects of this class. - add argument "-context ..." to "cmd::info" to pass the context object (so far the only place where the context-object is used) - object system configuration parameters changes: new: -class.configureparameter new: -object.configureparameter removed: -class.objectparameter
