Re-export os::IoDesc under io::IoDesc.

I've been trying to implement IoHandle for some convenience
wrappers.

I'm good w/ re-exporting IoDesc but IoDesc should not be clone (since the Fd can be closed from one of the clones). It should be duped in the case of posix at least.

If you need to reference connections from many places, I'd recommend the
Token in a Slab model. If you need to use the actual connection from
multiple threads, I'd say something has gone wrong.

I needed this to just work around some simple ownership headaches, but I figured out a different solution.

Updated the PR to remove the Clone commit.
