Log:
MFC r1.160:
When using m_dup(9) to copy more than MHLEN bytes of data, don't
create an mbuf chain that starts with a cluster containing just MHLEN
bytes. This happened because m_dup called m_get or m_getcl depending
on the amount of data to copy, but then always set the size available
in the first mbuf to MHLEN.
