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.
- 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()`
- `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.
`mrb_get_arg1()` raises `ArgumentError` if the method does not receive one
argument.
And replaces all `mrb_get_args(mrb, "o", &arg)` by the new function.
The binary sizes (gems are only `mruby-bin-mruby`) are reduced slightly in
my environment than before the introduction of new specifiers/modifiers
(5116789a) with this change.

BTW, I accidentally changed `tasks/toolchains/visualcpp.rake` at #4613,
so I put it back.
[Breaking changes]
Developers must use following APIs for accessing attributes of RRange
because RRange structure depends on boxing setting.
- mrb_range_beg
- mrb_range_end
- mrb_range_excl_p
The new API is:
int mrb_range_beg_len(mrb, range, &beg, &len, len, trunc)
The new argument `trunc` is a boolean value that specifies
whether the function truncates the range. The new return value
is an integer instead of a boolean, that is:
0: not a range
1: range with proper edges
2: out of range
To get the old behavior, you have to rewrite:
mrb_range_beg_len(mrb, range, &beg, &len, len)
to:
mrn_range_beg_len(mrb, range, &beg, &len, len, TRUE) == 1
[Breaking Change]
If the argument is always a string, then mrb_str_cat_str() can be
directly called instead of indirectly by mrb_str_append().
mrb_any_to_s(), mrb_obj_as_string(), mrb_inspect() always return a
string.
