Add mb_splitatpos_extpgs() to kern_mbuf.c. It is similar to m_split(),
but handles ext_pgs mbufs with anonymous pages. It does not duplicate
the m_pkthdr mbuf, since that could result in an mbuf with m_len == 0
and npgs == 0, which does not seem to be allowed by certain sanity
checks on ext_pgs mbuf chains.
For my uses, I do not need an m_pkthdr mbuf.
