octave: libinterp/corefcn/variables.cc annotate

annotate libinterp/corefcn/variables.cc @ 27873:020d0e8f7ac6

reafactor mlock, munlock, and mislocked functions * interpreter.h, interpreter.cc (interpreter::mlock, interpreter::munlock, interpreter::mislocked): Revamp. Provide versions that act on current function in the call stack (possibly skipping the first found) and versions of munlock and mislocked that accept function names. * call-stack.h, call-stack.cc (call_stack::current): Delete. (call_stack::current_function): New function. Change all uses of call_stack::current to use this function instead. (call_stack::caller): Delete. (call_stack::caller_function): New function, define in terms of current_function. Change all uses of call_stack::caller to use this function instead. (call_stack::mlock): Delete. * ov-fcn.h (octave_function::islocked): Now const. * pt-eval.h, pt-eval.cc (tree_evaluator::current_function, tree_evaluator::current_function_name, tree_evaluator::mlock): New argument, SKIP_FIRST. (tree_evaluator::munlock, tree_evaluator::mislocked): New functions. * variables.cc (Fmlock, Fmunlock, Fmislocked): Simplify. Decode arguments and call interpreter fucntions.
