SELinux: Add network port SID cache

Much like we added a network node cache, this patch adds a network port
cache. The design is taken almost completely from the network node cache
which in turn was taken from the network interface cache.  The basic idea is
to cache entries in a hash table based on protocol/port information.  The
hash function only takes the port number into account since the number of
different protocols in use at any one time is expected to be relatively
small.
