	[PATCH] [Bug #21814] Fix negative bignum modulo

	If modulo is zero, do not  apply bias even if the divisor is zero.
	`BIGNUM_POSITIVE_P` is true even on bignum zero.

Add support for `u128`, `U128`, `s128` and `S128` integers to `IO::Buffer`. (#15399)

Never shrink bignum on realloc

As far as I can tell, this only ever shrinks by one, and it's really not
worth the expensive realloc for that.

Use VWA for bignum

2025-12-05T14:21:17+00:00

Previously we only allocated bignums from the 40 byte sizepool, and
embedded bignum used a fixed size.

Implement rb_big_aref2.
Taking a small slice from large bignum was slow in rb_int_aref2.
