Sam Leffler 9967cafc49 Correct mbuf packet header propagation. Previously, packet headers ... were sometimes propagated using M_COPY_PKTHDR which actually did something between a "move" and a "copy" operation. This is replaced by M_MOVE_PKTHDR (which copies the pkthdr contents and "removes" it from the source mbuf) and m_dup_pkthdr which copies the packet header contents including any m_tag chain. This corrects numerous problems whereby mbuf tags could be lost during packet manipulations. These changes also introduce arguments to m_tag_copy and m_tag_copy_chain to specify if the tag copy work should potentially block. This introduces an incompatibility with openbsd which we may want to revisit. Note that move/dup of packet headers does not handle target mbufs that have a cluster bound to them. We may want to support this; for now we watch for it with an assert. Finally, M_COPYFLAGS was updated to include M_FIRSTFRAG|M_LASTFRAG.
