Move filedescriptor parsing code from net.c into qemu_parse_fd()
Move the parsing of a filedescriptor into a common function qemu_parse_fd() so others can use it as well. Have net.c call this function. v2: - moving qemu_parse_fd into cutils.c Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
