In the interest of using atomic FD_CLOEXEC in more places, I would
suggest making a change to this API:

This should be virNetClientDupFD(virNetClientPtr client, bool cloexec)
>

And this should be:
int virNetSocketDupFD(virNetSocketPtr sock, bool cloexec)
{
int fd;
if (cloexec)
fd = fcntl(F_DUPFD_CLOEXEC, sock->fd);
else
fd = dup(sock->fd);
if (fd < 0) {
...
and rely on gnulib's guarantee that fcntl(F_DUPFD_CLOEXEC) works. (Oh,
that means we need to import the fcntl module in bootstrap.conf).
