* Put ServerConnection into the BPrivate namespace as it should have been.

* Fixed completely broken error reporting; Write()/Read() will now return the
  proper error code (and ssize_t instead of int32).
* Reimplemented WaitForData() using poll() which is more efficient.
* Now uses BNetworkAddress to resolve the server address which also should now
  work with IPv6.
* Removed some unused headers.
* Minor coding style cleanup.
