bindat(2)/connectat(2): allow implicit EMPTYPATH for unix domain sockets

Summary

path specification.

As I understand it, bind() must create a new socket, as we use VOP_CREATE below. But then, how can we already have an fd for it?

It must create the vnode if not existing, but also it must check for the existence of the vnode, the EADDINUSE error when vp != NULL. As is, I think it is useful if only for completeness.

Hello all,

Got a testunit error on devel/aws-c-io and there is a PR opened https://github.com/awslabs/aws-c-io/issues/803

Any clues around this?

Thanks
