Log Message:
Pull up following revision(s) (requested by bouyer in ticket #674):
        sys/kern/uipc_mbuf.c: revision 1.132
m_split0(): If the newly allocated mbuf holds only the header,
don't forget to set m_len to 0. Otherwise whatever will compute the size
of this chain (including s_split() itself if called again on this chain)
will get it wrong, leading to various issues.
Bug exposed by the NFS server code with linux clients using TCP mounts.
