Title: std: Add experimental networking methods

The underlying I/O objects implement a good deal of various options here and
there for tuning network sockets and how they perform. Most of this is a relic
of "whatever libuv provides", but these options are genuinely useful.

It is unclear at this time whether these options should be well supported or
not, or whether they have correct names or not. For now, I believe it's better
to expose the functionality than to not, but all new methods are added with
an #[experimental] annotation.
