Alex Trotsenko a41c61fb2d QIODevice: implement a "zero-copy" strategy for buffered writes
It works as follows:

  - user calls write(const QByteArray &);
  - this function keeps a pointer to the chunk and calls a regular
    write(data, len);
  - write(data, len) calls a virtual writeData();
  - subclass calls a new QIODevicePrivate::write();
  - QIODevicePrivate::write() makes a shallow copy of
    the byte array.

Proposed solution is fully compatible with existing subclasses.
By replacing a call to d->writeBuffer.append() with d->write(),
subclasses can improve their performance.

Bump the TypeInformationVersion field in qtHookData, to notify the
Qt Creator developers that the offset of QFilePrivate::fileName was
changed and dumpers should be adapted.

This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.

Linux X11:

   * The user must be logged in to an active desktop; you can't run the
     autotests without a valid DISPLAY that allows X11 connections.

   * The tests are run against a KDE3 or KDE4 desktop.

   * Window manager uses "click to focus", and not "focus follows mouse". Many
     tests move the mouse cursor around and expect this to not affect focus
     and activation.

   * Disable "click to activate", i.e., when a window is opened, the window
     manager should automatically activate it (give it input focus) and not
     wait for the user to click the window.
