internal.h: aggregate internal functions.
...
Internal functions can only be called from within the library.
Functions listed in `mruby/internal.h` can be called from:
* core (src/*.c)
* gems (mrbgems/**/*.c)
But not from the application linked with `libmruby`.

numeric.h: remove obsolete functions.
...
- mrb_flo_to_fixnum()
- mrb_to_flo()
This commit removes weird abbreviation `_flo`.

numops.c: rename functions for addition and subtraction.
...
To more consistent names.
* mrb_num_plus() -> mrb_num_add()
* mrb_num_minus() -> mrb_num_sub()
Since no one seems to use those functions, there should be no problem.
We added migration macros for compatibility for safety.

numeric.c: merge mrb_as_float implementation to mrb_ensure_float_type.

Since they are basically duplicated functionality. `mrb_as_float` is now
a macro defined using `mrb_ensure_float_type`; #5620

numeric.c: restore fmt argument for backward compatibility.
...
`mrb_float_to_str()` used to take `fmt` argument. We thought no one used
the function, and OK to remove the argument. But at least `mruby-redis`
gem used the function.

fp_fmt.c: remove mrb_float_to_cstr().

fmt_fp.c: replace with public domain float format routine; ref #5448

Changes:
- support `double`
- support `#` (alt_form) modifier
- small refactoring

Global renaming regarding integer and float.
...
Consistent number conversion function names:
* `mrb_value` to immediate (C) value
* `mrb_int()` -> `mrb_as_int()`
* `mrb_to_flo()` -> `mrb_as_float()`
* `mrb_value` to `mrb_value` (converted)
* `mrb_to_int()'
* `mrb_Integer()` - removed
* `mrb_Float()` -> `mrb_to_float`
Consistent function name (avoid `_flo` suffix):
* `mrb_div_flo()` -> `mrb_div_float`

platforms.

- Integrate `Fixnum` and `Integer`
- Remove `Integral`
- `int / int -> int`
- Replace `mrb_fixnum()` to `mrb_int()`
- Replace `mrb_fixnum_value()` to `mrb_int_value()`.

Rename float configuration option names.
...
- `MRB_WITHOUT_FLOAT` => `MRB_NO_FLOAT`
- `MRB_USE_FLOAT` => `MRB_USE_FLOAT32`
The former is to use `USE_XXX` naming convention. The latter is to make
sure `float` is 32bit float and not floating point number in general.

Fix FIXABLE_FLOAT() on MRB_INT64; ref #4566
...
Normal `TYPED_FIXABLE(f,mrb_float)` does not work on 64bit int from
casting problems. The new approach works well, but assumes two's
complement and IEEE-754 floating point numbers.

Export mrb_int_value that converts mrb_float to Fixnum.
...
Or `Float` if `mrb_float` value is too big (or too small) to fit in
`mrb_int`. The `_int_` in `mrb_int_value` means `Integral` module, which
represents integer-like values in mruby.

Version checking is not reliable - especially with Clang.
E.g. Apple's Clang (Xcode) uses different version numbers.
A feature check (__has_builtin) is the recommened way.

macro which may be used in other files.
