#### Before this patch:
```ruby
Integer("_1") #=> 1
"_1".to_i #=> 1
```
#### After this patch (same as Ruby):
```ruby
Integer("_1") #=> ArgumentError
"_1".to_i #=> 0
```

shuujii/fix-that-String-to_f-accepts-consecutive-_-as-a-numeric-expression
Fix that `String#to_f` accepts consecutive `_` as a numeric expression
|
|
Consecutive `_` is not allowed as a numeric expression:
1_2__3 #=> SyntaxError
Float("1_2__3") #=> ArgumentError
Integer("1_2__3") #=> ArgumentError
"1_2__3".to_i #=> 12
But `String#to_f` accept it, so I fixed the issue.
Before this patch:
"1_2__3".to_f #=> 123
After this patch:
"1_2__3".to_f #=> 12

Fix keyword arguments not be obtained with `mrb_get_args()`; Fix #4754
|
|
#### Before this patch:
```
$ bin/mruby -e 'Float("1_a")'
-e:1: invalid string for float(a) (ArgumentError)
```
#### After this patch:
```
$ bin/mruby -e 'Float("1_a")'
-e:1: invalid string for float("1_a") (ArgumentError)
```

If ":" is after "|" and there is no "?" or "*", the keyword argument
could not be obtained and it was not initialized with `undef`.
For example: "|oo:"
|
|
* The allocated memory is guaranteed to be aligned for any data type (it was
not guaranteed when string type is embed).
* Make allocation size exactly specified size (does not allocate space for a
null byte).

Add assertion to `RVALUE` size
|
|
The bit width terminology is unified to `BIT` according to `MRB_INT_BIT`
and `CHAR_BIT`. Also the bit position terminology is unified to `BIT_POS`.

Previously, `mrb_int` was used as the type that represents the buffer size
on memory, but the sizes of `RString` and `RArray` exceed 6 words when
`MRB_INT64` is enabled on 32-bit CPU.
I don't think it is necessary to be able to represent the buffer size on
memory that exceeds the virtual address space. Therefore, for this purpose,
introduce `mrb_ssize` which doesn't exceed the sizes of `mrb_int` and
pointer.
I think all `mrb_int` used for this purpose should be changed to
`mrb_ssize`, but currently only the members of the structures (`RString`,
`mrb_shared_string`, `RArray` and `mrb_shared_array`) are changed.

- Keep `MRB_STR_ASCII` flag.
- Avoid a string object creation.

Fix argument specs to `Kernel`
|
|
This feature was reverted from Ruby 2.7.

On cases like `a.unshift(*a)`.

- `Fixnum#to_s`, `Fixnum#inspect`
- `Float#to_s`, `Float#inspect`
- `NilClass#to_s`, `NilClass#inspect`
- `FalseClass#to_s`, `FalseClass#inspect`
- `TrueClass#to_s`, `TrueClass#inspect`
- `Time#to_s`, `Time#inspect`

### Benchmark (with `MRB_UTF8_STRING`)
```
$ mruby -e '
COUNT = 150000
SIZE = 10000
strs = Array.new(COUNT) do
s = "a" * SIZE
s.size # set `MRB_STR_ASCII` flag
s
end
i = 0
t = Time.now
while i < COUNT
strs[i][-2..-1] = ""
i += 1
end
printf "%.2f sec\n", Time.now - t
'
1.10 sec # before
0.07 sec # after
```

### Benchmark (with `MRB_UTF8_STRING`)
```ruby

COUNT = 300000
SIZE = 10000
s = "a" * SIZE
s.size # set `MRB_STR_ASCII` flag
i = 0
while i < COUNT
s[-1]
i += 1
end
```
#### Before this patch:
```
$ time mruby benchmark.rb
2.06 real 2.05 user 0.00 sys

#### After this patch:

- Use `mrb_sym_name_len` instead of `mrb_sym_name` (class name should not
be escaped).
- Avoid `mrb_str_dup` (it is unnecessary to be shared string because it is
changed).

shuujii/sHARED-string-is-not-required-when-sharing-POOL-string
SHARED string is not required when sharing POOL string
|
|
The heap string buffer of POOL string always exists, does not need to be
released, and read only, so it can be shared as NOFREE string.
|
|
Because it may not create `struct mrb_shared_string`.
|

Keyword arguments can now be retrieved with the `:` specifier and
`mrb_kwargs` data.
For the interface, I referred to CRuby's `rb_get_kwargs()`.
For implementation, I referred to `OP_KARG` or etc.

This is an experimental changes in Ruby 2.7.

These are included in `mruby.h`.
As a background, if `enable_cxx_abi` is specified, the macro that
defines the maximum value in `stdint.h` is undefined depending on the
environment.
- Confirmed with gcc on FreeBSD 12.0 and mingw32-gcc available on
FreeBSD.
- `INTPTR_MAX`, `INT64_MAX` and `UINT64_MAX` are defined by `cstdint`
added in C++11. But `toolchains :gcc` adds `-std=c++03`, so the macros
are not defined.
- To have these defined in `C++03`, `__STDC_CONSTANT_MACROS` must be
defined in advance. This is already done by `mruby.h`.

Also fix document about type of the first argument.
