octave: libinterp/corefcn/variables.cc annotate

annotate libinterp/corefcn/variables.cc @ 23699:b29904962d2d

deprecate some global functions that access the symbol table * variables.h, variables.cc (clear_mex_functions, clear_function, clear_variable, clear_symbol, lookup_function_handle, get_global_value, set_global_value, get_top_level_value, set_top_level_value): Deprecate. Eliminate all uses in Octave.
