nsf.c: - fix case, where NsfDStringPrintf() failed (when print llength including \0 was 1 byte longer than print buffer) - make sure, that the list kept for the cached parameter is just built from unshared objects; otherwise Tcl append will abort nx.tcl: - new package "nx::volatile" - don't define configure parameter "-volatile" per default; use "package req nx::volatile" instead - don't define per method "volatile" per default; use "::nsf::method::require ::nx::Object volatile" instead - get rid of -volatile in nx.tcl and serializer - update/extend regression test
