[Click] add TCPFragmenter element

[Beyers Cronje]

Hi Cliff,

A small comment from my side, it does not seem that the element takes ip
header options in consideration when gaining a pointer to the tcp header.
I would change:

const click_tcp *tcp = reinterpret_cast<const click_tcp *>(ip + 1);

To:

const click_tcp *tcp = p->tcp_header();

This ensures accurate offset to the tcp header even when ip options are
present.
