The NetLabel address selector mechanism has a problem where it can get
mistakenly remove the wrong selector when similar addresses are used. The
problem is caused when multiple addresses are configured that have different
netmasks but the same address, e.g. 127.0.0.0/8 and 127.0.0.0/24. This patch
fixes the problem.

This patch extends the NetLabel traffic labeling capabilities to individual
packets based not only on the LSM domain but the by the destination address
as well. The changes here only affect the core NetLabel infrastructre,
changes to the NetLabel KAPI and individial protocol engines are also
required but are split out into a different patch to ease review.

Create an ordered IP address linked list mechanism similar to the core
kernel's linked list construct. The idea behind this list functionality
is to create an extensibile linked list ordered by IP address mask to
ease the matching of network addresses. The linked list is ordered with
larger address masks at the front of the list and shorter address masks
at the end to facilitate overriding network entries with individual host
or subnet entries.
