thorpej a0e791807e Eliminate use of dtom() from the network code, allowing more flexible
use of mbuf external storage and increasing performance (by eliminating
an m_pullup() for clusters in the IP reassembly code).

Changes from Koji Imada <koji@math.human.nagoya-u.ac.jp>, in PR #3628
and #3480, with ever-so-slight integration changes by me.
