SELinux: Add a network node caching mechanism similar to the sel_netif_*() functions
This patch adds a SELinux IP address/node SID caching mechanism similar to the
sel_netif_*() functions. The node SID queries in the SELinux hooks files are
also modified to take advantage of this new functionality. In addition, remove
the address length information from the sk_buff parsing routines as it is
redundant since we already have the address family.
