QmlJsInspector: remove private header dependencies

A copy of the client debugging code is made in src/libs/qmljsdebugclient/
(this comes from the qt code from commit 65642dd343bf61)

So the qmljsinspector plugin does not require anymore Qt private headers.

+  \class QPacketProtocol
+  \internal
+
+  \brief The QPacketProtocol class encapsulates communicating discrete packets
+  across fragmented IO channels, such as TCP sockets.
+
+  QPacketProtocol makes it simple to send arbitrary sized data "packets" across 
+  fragmented transports such as TCP and UDP.
+
+  As transmission boundaries are not respected, sending packets over protocols
+  like TCP frequently involves "stitching" them back together at the receiver.
+  QPacketProtocol makes this easier by performing this task for you.  Packet
+  data sent using QPacketProtocol is prepended with a 4-byte size header
+  allowing the receiving QPacketProtocol to buffer the packet internally until
+  it has all been received.  QPacketProtocol does not perform any sanity
+  checking on the size or on the data, so this class should only be used in
+  prototyping or trusted situations where DOS attacks are unlikely.
+
+  QPacketProtocol does not perform any communications itself.  Instead it can
+  operate on any QIODevice that supports the QIODevice::readyRead() signal.  A
+  logical "packet" is encapsulated by the companion QPacket class.  The
+  following example shows two ways to send data using QPacketProtocol.  The
+  transmitted data is equivalent in both.
+
+  \code
+  QTcpSocket socket;
+  // ... connect socket ...
+
+  QPacketProtocol protocol(&socket);
+
+  // Send packet the quick way
+  protocol.send() << "Hello world" << 123;
+
+  // Send packet the longer way
+  QPacket packet;
+  packet << "Hello world" << 123;
+  protocol.send(packet);
+  \endcode
+
+  Likewise, the following shows how to read data from QPacketProtocol, assuming
+  that the QPacketProtocol::readyRead() signal has been emitted.
+
+  \code
+  // ... QPacketProtocol::readyRead() is emitted ...
+
+  int a;
+  QByteArray b;
+
+  // Receive packet the quick way
+  protocol.read() >> a >> b;
+
+  // Receive packet the longer way
+  QPacket packet = protocol.read();
+  p >> a >> b;
+  \endcode
