iov: Introduce iov_tail_clone() and iov_drop_header().
These utilities enhance iov_tail manipulation, useful for
efficient packet processing by enabling iovec array cloning and
header stripping without data copies.
- iov_drop_header(): Discards a specified number of bytes from the
beginning of an iov_tail by advancing its internal offset and pruning
consumed elements.
- iov_tail_clone(): Clone an iov_tail into an iovec array, adjusting the
first iovec entry to remove the iov_tail offset.
