Log Message:
Revert the functional change in rev 1.38; permit a msg_iovlen of 0.
There are two reasons for this:
* We should be able to pass file descriptors without sending any data.
* We could send zero-length iovecs anyway (but we shouldn't have to do this).
Also, msg_iovlen is already a u_int, so delete a bunch of casts.
