Adds netstat command line argument to display slash-separated pair of
the id and name of the process that owns the socket. User must have
superuser privileges to see information on non-owned sockets.
This implementation of netstat presents an overview of existing network
sockets. It directly reads the exposed sockets from /proc/net/. Current
support is limited to information regarding TCP and UDP connections.
Future improvements could include presenting information regarding
local sockets.
