- nsf.c: * refined refcounting debugging * fixed various refcounting bugs, especially in error cases. * added explicit INCR_REF_COUNTs on Tcl_Objs with 0-refCount to ease debugging
- nsf.c: * added flag "-array" to nsf::var::set such we have now "::nsf::var::set ?-array? object varName ?value?" With "-array", nsf::var::set behaves like "array get" or "array set" (on instance variables) * use "::nsf::var::set -array" in serializer symmetrically to scalar case * extended regression test
