Add three new read-only socket options, which allow regression tests
and other applications to query the state of the stack regarding the
accept queue on a listen socket:
SO_LISTENQLIMIT Return the value of so_qlimit (socket backlog)
SO_LISTENQLEN Return the value of so_qlen (complete sockets)
SO_LISTENINCQLEN Return the value of so_incqlen (incomplete sockets)
Minor white space tweaks to existing socket options to make them
consistent.
Discussed with: andre
