move non-member octave_value operator functions to octave namespace * ov.h, ov.cc (unary_op, binary_op, cat_op, colon_op): New functions in octave namespace that replace do_unary_op, do_binary_op, do_cat_op, and do_colon_op, respectively. (do_unary_op, do_binary_op, do_cat_op, do_colon_op): Deprecate global functions. Forward to corresponding new functions in octave namespace. * bsxfun.cc, cellfun.cc, data.cc, dot.cc, fft.cc, oct-stream.cc, stack-frame.h, tril.cc, ov-base-diag.cc, ov-bool.cc, ov-class.cc, ov-complex.cc, ov-float.cc, ov-flt-complex.cc, ov-intx.h, ov-lazy-idx.h, ov-magic-int.cc, ov-perm.cc, ov-range.cc, ov-scalar.cc, oct-lvalue.cc, oct-lvalue.h, pt-binop.cc, pt-cbinop.cc, pt-colon.cc, pt-eval.cc, pt-tm-const.cc, pt-unop.cc: Change all uses.
