06:46 AM Ruby Feature #22483: Region forms of String#bit_get

For what it's worth, almost all such pairs in Ruby are get/set.
The closest existing API, byte access to a String, is `String#getbyte` / `#setbyte`.
Among positional read/write methods, `IO::Buffer` has `IO::Buffer#get_value` / `se... mame (Yusuke Endoh)

05:01 AM Ruby Feature #22483: Region forms of String#bit_get

If `bit_get` can read a bit region as an Integer, I think there should also be an API that writes an Integer back into a region. For example:
```ruby
s = "\x8A".b
v = s.bit_get(4, 4) # read the upper 4 bits (0x8)
v = (v + 1) & 0... mame (Yusuke Endoh)

06:58 PM Ruby Revision 799fd1f5 (git): Allocate a frozen copy of a shareable string with the terminator of its encoding

str_new_frozen_buffer copied a shareable string with room for a 1-byte
terminator, so String#-@ on a shareable UTF-16 or UTF-32 string
returned a string without room for its terminator.

06:58 PM Ruby Revision b5e415db (git): Allocate the result of String#slice! with the terminator of its encoding

[Bug #22517]
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
(cherry picked from commit 8d2bec3b97c3198e49387180b83ae34b60b364c9) mame (Yusuke Endoh)

06:58 PM Ruby Revision 1b973182 (git): Assert that str_enc_copy_direct is used on a string with room for the terminator

str_enc_copy_direct does not adjust the room for the terminator, so the
string must already have room for the terminator of the new encoding.

06:58 PM Ruby Revision b4b36502 (git): Compute the buffer size of unpack("m") without overflow

(send - s + 3) * 3 / 4 overflowed for an input of about 700 MB where
long is 32-bit. Divide before multiplying, as each 4 characters decode
to at most 3 bytes.
