Need to be able to chmod the socket

[njaard]

After I call Http::bind(), I need to be able to chmod the file descriptor appropriately.

In theory, something like this:

let s = hyperlocal::server::Http::new()
  .bind(&address["unix:".len()..], new_service)?;
libc::fchmod(s.listener.as_raw_fd(), 0o777);

But this isn't possible because s.listener is not pub.

Maybe a function Http::bind_with_permissions could be used to atomically bind and chmod?

[njaard]

POSIX doesn't offer an atomic "bind and chmod" for unix domain sockets, and I think a more generalized solution of "let me access the low level object" is warranted.

[moosingin3space]

Such as an as_raw_fd function on Server?

@moosingin3space @njaard I just published 0.5.0 which includes a change to expose this
