Subject: Change net/socket.c to use socket_*() functions

Use socket_*() functions from include/qemu/sockets.h instead of
listen()/bind()/connect()/parse_host_port(). socket_*() fucntions are
QAPI based and this patch  performs this api conversion since
everything will be using QAPI based sockets in the future. Also add a
helper function socket_address_to_string() in util/qemu-sockets.c
which returns the string representation of socket address. Thetask was
listed on http://wiki.qemu.org/BiteSizedTasks page.
