Support MSG_DONTWAIT in send*(2).

Description

Support MSG_DONTWAIT in send*(2).

As it does for recv*(2), MSG_DONTWAIT indicates that the call should
not block, returning EAGAIN instead. Linux and OpenBSD both implement
this, so the change makes porting easier, especially since we do not
return EINVAL or so when unrecognized flags are specified.
