History
Sam Leffler 9c855a36c1 Introduce the notion of "persistent mbuf tags"; these are tags that stay 
with an mbuf until it is reclaimed.  This is in contrast to tags that
vanish when an mbuf chain passes through an interface.  Persistent tags
are used, for example, by MAC labels.

Add an m_tag_delete_nonpersistent function to strip non-persistent tags
from mbufs and use it to strip such tags from packets as they pass through
the loopback interface and when turned around by icmp.  This fixes problems
with "tag leakage".
