And refactor some code a bit, don't use bytes.Clone where type-specific
helpers may be used instead.
Close#2907.

It's a bug since Prefix is shared between all iterator items and
appending is not enough. If prefix has enough capacity, then new slice
won't be created and the previous item's prefix will be changed.
This commit fixes the following test failure caused by moving from
bytes.Clone to slice.Copy:
