Gustaf A. Neumann <neumann@Gustaf-A-Neumanns-iMac.local>

- nsf.c: changed handling of cmdPtrs in callstack content. * we use now explicit reference counting using NsfCommandPreserve/NsfCommandRelease * as a consequence, we do not need the following functions Nsf_DeleteCommandFromToken() and CallStackClearCmdReferences() any more. * the flag NSF_CSC_OBJECT_ACTIVATED is not needed anymore and was removed

- removed a small memory leak when a destroy method of an object o

deletes its grandparents namespace, containing also this class of o

(and its methods). Significantly eased by the change above.

Gustaf Neumann <neumann@wu-wien.ac.at>

- nsf.c: fixed a nasty bug within namespace deletion, when a deletion of one tcl cmd caused implicit deletions of other cmds in the same namespace. The classical idiom for looking over hash tables with Tcl_GetHashValue() and Tcl_NextHashEntry(hSrch) can lead to crashes (and has different behavior depending on the number of buckets). - added regression test

- Make CompiledColonVarFetch() more robust in case of

half initialized objects (create vartable on the fly if needed)

- allow empty parameter options in parameter parser

- removed nsf::parametersfromslots (became simple, part of objectparameter now)

- removed hardcoded objectparameter (attributes, volatile and noinit)

- updated regression test
