01:51 PM Ruby Revision 90e7ab3a (git): [ruby/json] ResumableParser: fix handling of incomplete unicode escape

`spe` is the string end, so if the escape is incomplete, it doesn't
mean we reached the end of stream, hence it's a syntax error, not
an EOS error.

08:52 AM Ruby Revision 334b4ffa (git): [DOC] Clarify `rb_len_t` entry in NEWS.md

byroot (Jean Boussier)

07:52 AM Ruby Feature #22400: Use rb_long_t for lengths so that String and Array can exceed 2GiB on mswin

@hsbt what's the migration path for C extensions? I don't see a `HAVE_RB_LEN_T`, should we provide one so that extensions can declare:
```c
#ifndef HAVE_RB_LEN_T
typedef long rb_len_t;
typedef unsigned long rb_ulen_t;
#endif
``` byroot (Jean Boussier)
