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.
