andre 143b5d29e0 Add an API for jumbo mbuf cluster allocation and also provide 
4k clusters in addition to 9k and 16k ones.

 struct mbuf *m_getjcl(int how, short type, int flags, int size)
 void *m_cljget(struct mbuf *m, int how, int size)

m_getjcl() returns an mbuf with a cluster of the specified size attached
like m_getcl() does for 2k clusters.

m_cljget() is different from m_clget() as it can allocate clusters
without attaching them to an mbuf.  In that case the return value
is the pointer to the cluster of the requested size.  If an mbuf was
specified, it gets the cluster attached to it and the return value
can be safely ignored.

For size both take MCLBYTES, MJUM4BYTES, MJUM9BYTES, MJUM16BYTES.
