From 5db5f44cb4b7f24b9e0efdefc9015e36b7c34881 Mon Sep 17 00:00:00 2001
From: Orit Wasserman <owasserm@redhat.com>

Subject: Separate inet_connect into inet_connect (blocking) and
 inet_nonblocking_connect

No need to add non blocking parameters to the blocking inet_connect
add block parameter for inet_connect_opts instead of using QemuOpt "block".
