Roman Khimov	c7b623cc38	*: drop pkg/util/slice, use slices.Reverse ... This also removes bigint.FromBytesUnsigned(), it's not used very often and it's somewhat misleading in the bigint package (which is supposed to use a very specific enconding).

Roman Khimov	dfd4f6978f	bigint: don't reallocate big.Int in ToBytes(), fix #2864 ... In some cases n.Add() can reuse the []Word buffer and n.Sub() reallocate it away. If that happens, we're out of luck with 0.99.0+ versions (since 3945e81857). I'm not sure why it does that, bit width doesn't change in most of the cases and even if it does, we still have enough of it in cap() to hold the old Abs() value (when we have a negative value we in fact decreate its Abs() first and increase it back afterwards). Still, that's what we have. So when we have processTokenTransfer() doing Neg/Neg in-place its value is not affected, but the original []Word bits that are reused by amount value are (they're shared initially, Amount: *amount). name old time/op new time/op delta ToPreallocatedBytes-8 65.8ns ± 2% 45.6ns ± 2% -30.73% (p=0.008 n=5+5) name old alloc/op new alloc/op delta ToPreallocatedBytes-8 0.00B 0.00B ~ (all equal) name old allocs/op new allocs/op delta ToPreallocatedBytes-8 0.00 0.00 ~ (all equal)	2023-01-10 22:51:45 +03:00
