Move bigint implementation files to mruby-bigint
...
Users can now switch to their own implementation of GEM.
However, we do not guarantee that this will not be a problem in the current situation.
This may need to be improved in the future.

src/bigint.c: implement multi-precision integer.
...
To enable multi-precision integer support, you need to link
`mruby-bigint` mrbgem. The gem itself is empty but it turns on
the "bigint" support.

numeric_ext.c: add Integer#pow() method.

Organize the include of header files
...
- `#include <math.h>` is done in `mruby.h`.
Eliminate the need to worry about the `MRB_NO_FLOAT` macro.
- Include mruby header files before standard header files.
If the standard header file is already placed before `mruby.h`, the standard header file added in the future tends to be placed before `mruby.h`.
This change should some reduce the chances of macros that must be defined becoming undefined in C++ or including problematic header files in a particular mruby build configuration.

numeric_ext.c: use mrb_integer instead of mrb_as_int.

`mrb_as_int` implicitly converts the value into the integer, but those
methods are defined for Integer class so that the value should always be
integers.

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`

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.

Avoid including presym.inc in existing header files

Addressed an issue where existing programs linking `libmruby.a` could only
be built by adding `<build-dir>/include` to compiler's include path.

Reorganize Integer system.
...
- Integrate `Fixnum` and `Integer`
- Remove `Integral`
- `int / int -> int`
- Replace `mrb_fixnum()` to `mrb_int()`
- Replace `mrb_fixnum_value()` to `mrb_int_value()`.
- Use `mrb_integer_p()` instead of `mrb_fixnum_p()`

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.

Integrate Integral#chr (Fixnum#chr) to mruby-string-ext
...
Because they're defined in both `mruby-string-ext` and `mruby-numeric-ext`
(they seem more natural to define in N, but `mruby-string-ext` depends on
`Integral#chr`).

Remove implicit conversion using to_int method.
...
The ISO standard does not include implicit type conversion using
`to_int`. This implicit conversion often causes vulnerability.
There will be no more attacks like #4120 .
In addition, we have added internal convenience method `__to_int` which
does type check and conversion (from floats).
