Merge branch 'master' of scm.dev.nokia.troll.no:qt/oslo-staging-1 into master-integration

* 'master' of scm.dev.nokia.troll.no:qt/oslo-staging-1:
  Cannot enter text through character viewer on Mac (Cocoa)
  QNAM HTTP: Remove eatWhitespace() hack
  QNAM: Fix namespaced compilation
  Revert the addition of the test of QtTest's random feature.
  QAbstractSocket: Remove warning
  QNAM Zerocopy: Benchmark
  tst_qbytearray: Auto test for reserve()
  tst_qiodevice: Add peek()ing auto test
  tst_qnetworkreply: Zerocopy auto test
  tst_qhttpnetworkconnection: Pipelining auto test
  QNAM Zerocopy: QNAM implementation part
  QNAM Zerocopy: HTTP implementation part
  QAbstractSocket: Enable Unbuffered OpenMode for TCP
  QNativeSocketEngine: Fix wrong debug output
  Added QObject::senderSignalIndex()
  Cleanup the connection list logic in QObject::sender
  Fixed linking against libQtTest on Mac.
  Added -random option to tests, making the test cases within a test execute in arbitrary order. Very useful for avoiding test cases being dependent on the running order.

+    Returns the meta-method index of the signal that called the currently
+    executing slot, which is a member of the class returned by sender().
+    If called outside of a slot activated by a signal, -1 is returned.
+
+    For signals with default parameters, this function will always return
+    the index with all parameters, regardless of which was used with
+    connect(). For example, the signal \c {destroyed(QObject *obj = 0)}
+    will have two different indexes (with and without the parameter), but
+    this function will always return the index with a parameter. This does
+    not apply when overloading signals with different parameters.
+
+    \warning This function violates the object-oriented principle of
+    modularity. However, getting access to the signal index might be useful
+    when many signals are connected to a single slot.
+
+    \warning The return value of this function is not valid when the slot
+    is called via a Qt::DirectConnection from a thread different from this
+    object's thread. Do not use this function in this type of scenario.
