[json] Make json Ractor safe

[json] JSON_parse_float: Fix how to convert number

2020-12-21T13:10:43+00:00

Stop BigDecimal-specific optimization.  Instead, it tries the conversion
methods in the following order:

1. `try_convert`,
2. `new`, and
3. class-named function, e.g. `Foo::Bar.Baz` function for `Foo::Bar::Baz` class

If all the above candidates are unavailable, it fallbacks to Float.

Implement a freeze: parser option

2020-10-20T12:40:25+00:00

If set to true all parsed objects will be
immediately frozen, and strings will be
deduplicated if the Ruby implementation
allows it.

[flori/json] Use frozen string for hash key

2020-07-01T09:47:51+00:00

When use non-frozen string for hash key with `rb_hash_aset()`, it will duplicate and freeze it internally.
To avoid duplicate and freeze, this patch will give a frozen string in `rb_hash_aset()`.

ext/json/parser/parser.rl: Use "signed" char to contain negative values

2019-10-04T22:00:57+00:00

char is not always signed.  In fact, it is unsigned in arm.
