  \class QDumper
  \brief Helper class for producing "nice" output in Qt Creator's debugger.

  \internal

  The whole "custom dumper" implementation is currently far less modular
  than it could be. But as the code is still in a flux, making it nicer
  from a pure archtectural point of view seems still be a waste of resources.

  Some hints:

  New dumpers for non-templated classes should be mentioned in
  \c{qDumpObjectData440()} in the  \c{protocolVersion == 1} branch.

  Templated classes need extra support on the IDE level
  (see plugins/debugger/gdbengine.cpp) and should not be mentiond in
  \c{qDumpObjectData440()}.

  In any case, dumper processesing should end up in 
  \c{handleProtocolVersion2and3()} and needs an entry in the bis switch there.

  Next step is to create a suitable \c{static void qDumpFoo(QDumper &d)}
  function. At the bare minimum it should contain something like:


  \c{
    const Foo &foo = *reinterpret_cast<const Foo *>(d.data);

    P(d, "value", ...);
    P(d, "type", "Foo");
    P(d, "numchild", "0");
  }


  'P(d, name, value)' roughly expands to:
        d << (name) << "=\"" << value << "\"";

  Useful (i.e. understood by the IDE) names include:

  \list
    \o "name" shows up in the first column in the Locals&Watchers view.
    \o "value" shows up in the second column.
    \o "valueencoded" should be set to "1" if the value is base64 encoded.
        Always base64-encode values that might use unprintable or otherwise
        "confuse" the protocol (like spaces and quotes). [A-Za-z0-9] is "safe".
        A value of "3" is used for base64-encoded UCS4, "2" denotes 
        base64-encoded UTF16.
    \o "numchild" return the number of children in the view. Effectively, only
        0 and != 0 will be used, so don't try too hard to get the number right.
  \endlist

  If the current item has children, it might be queried to produce information
  about thes children. In this case the dumper should use something like

  \c{
    if (d.dumpChildren) {
        d << ",children=[";
   }
