add send_vectored for unix socket #69915

@contrun As far as I can tell, the changes that @LinkTed made in #69864 do use libc::sendmsg. I think it may make sense to use a common implementation here.

contrun · 2020-03-12T02:11:58Z

@LinkTed @joshtriplett Thanks. I will close this one.

Ralith · 2020-04-26T19:05:18Z

It might be nice to get this in separately from #69864, since just send_vectored doesn't require working out an API for ancillary data and can presumably be reviewed and merged much more quickly.
