Doc: Fix network/torrent example to work on Qt 5

This change fixes two issues in the torrent example:

    - Correctly use a query constructed from the announce url to fetch
      the list of peers (using QUrlQuery).
    - Reimplement QAbstractSocket's connectToHost() and
      disconnectFromHost() which are virtual in Qt 5, instead of
      of using the protected connectToHostImplementation() /
      disconnectFromHostImplementation() slots.

Also removes a warning about deprecation of QHttp class as it's no
longer used in this example.
