Yukihiro "Matz" Matsumoto 51b11a6919 mruby-rational: add comments 
We used `mrb_bint_mul(mrb, n, ONE)` to normalize `n`. The code confused
ChatGPT that could not read the intention.

dearblue 8ecfacefca Prohibit Class#allocate in a different way 
The method introduced by #5979 causes a fault by swapping classes.

```console
% bin/mruby -e 'Method = Proc; p Object.method(:inspect)'
zsh: segmentation fault (core dumped)  bin/mruby -e 'Method = Proc; p Object.method(:inspect)'
```

After applying this patch, a `TypeError` exception will be raised.

```console
% bin/mruby -e 'Method = Proc; p Object.method(:inspect)'
trace (most recent call last):
        [1] -e:1
-e:1:in method: allocation failure of Proc (TypeError)
```

However, if the `mrb_vtype` is the same object, the same care must still be taken as before.

```console
% bin/mruby -e 'Method = Binding; p method(:puts).eval("12345")'
trace (most recent call last):
        [1] -e:1
-e:1:in eval: wrong argument type nil (expected Proc) (TypeError)
```

dearblue d3128ce58a Allow Class#allocate to be prohibited 
Calling `Class#allocate` with `UnboundMethod#bind_call` usually succeeds without problems.
If this behavior does not make us happy, we can now prohibit it with `MRB_SET_INSTANCE_TT(klass, MRB_TT_UNDEF)`.

At the same time, it applies to the `Binding`, `Complex`, `Data`, `Float`, `Integer`, `Method`, `Rational` and `UnboundMethod` classes.

Yukihiro "Matz" Matsumoto 9c5dc42e59 small cosmetic changes. 
I prefer `i++` style unless absolutely necessary.
This commit is an addition to 41e4148.

dearblue ac22a63ae3 Call functions directly from mrb_ensure_float_type() 
ref. commit 7f40b645d2

Currently, the build configurations `MRB_USE_COMPLEX` and `MRB_USE_RATIONAL` are not listed in the documentation.
In other words, they are hidden settings.
They are defined in `mrbgems/mruby-{complex,rational}/mrbgem.rake`.
So this patch assumes that it is safe to refer to these functions in core-gems directly from core functions.

However, applications that link with `libmruby_core.a` will have compatibility issues.
In fact, `mrbgems/mruby-bin-mrbc` links with `libmruby_core.a`, so I had to prepare a dummy function.
