Andre Oppermann 4da8443133 Add m_copymdata(struct mbuf *m, struct mbuf *n, int off, int len, 
int prep, int how).

Copies the data portion of mbuf (chain) n starting from offset off
for length len to mbuf (chain) m.  Depending on prep the copied
data will be appended or prepended.  The function ensures that the
mbuf (chain) m will be fully writeable by making real (not refcnt)
copies of mbuf clusters.  For the prepending the function returns
a pointer to the new start of mbuf chain m and leaves as much
leading space as possible in the new first mbuf.
