numeric.c: function renaming.
...
- `mrb_num_div_int(mrb,x,y)` -> `mrb_div_int(mrb,x,y)`
- `mrb_num_div_flo(mrb,x,y)` -> `mrb_div_flo(x,y)`
They are internal function not supposed to be used outside of the core.

It removes non-static function, so that strictly saying, it's
an incompatible change. But the function was added recently and I am
sure no one uses it yet.

Minimize the changes in #5277
...
Instead of including `mruby/presym.h` everywhere, we provided the
fallback `mruby/presym.inc` under `include/mruby` directory, and specify
`-I<build-dir>/include` before `-I<top-dir>/include` in `presym.rake`.
So even when someone drops `-I<build-dir>/include` in compiler options,
it just compiles without failure.
