Proposal: add ByteString support to unix:System.Posix.IO API

We don't need to stop-the-world, but we can at least agree a general
policy in advance of starting to make such changes.
In this specific case the unicode/byte mismatch means there's a strong
case for doing it anyway; but one might argue for replacing String with
[Char8] instead of removing it completely. Again, if we had a generally
agreed approach to what "string" types to support, we could justify
individual decisions like this easily by reference to that policy.

	Which was my point.  If you're going to deprecate Strings, do so
across the
	board in an organized manner --- not via ad hoc deprecations to

The only problem with that is that ad hoc deprecations are achievable by
individual library maintainers, while a "stop-the-world" approach won't,
I think, work.
