net: Improve error handling
Take a pass at plumbing errors through to the users of the network stack Currently only the start() function errors will be returned from NetLoop(). recv() tends not to have errors, so that is likely not worth adding. send() certainly can return errors, but this patch does not attempt to plumb them yet. halt() is not expected to error.
