octave: libinterp/corefcn/variables.cc annotate

annotate libinterp/corefcn/variables.cc @ 25762:97ea2329d5d8

Use nested functions to prevent leaking globals in BIST tests. * cellfun.cc (Fcellfun, Farrayfun): Use nested functions with access to enclosing functions variables, rather than globals, to pass pass information out of function and in to BIST test. * variables.cc (Fisglobal): Clear global variable created during BIST test.
