QMap used to use a skiplist in Qt 4.x, which has variable sized nodes and we can thus not optimise using custom allocators. The rewrite now uses a red-black tree, and all allocations and tree operations happen in the cpp file. This will allow us to introduce custom allocation schemes in later versions of Qt. Added some more tests and a benchmark. Memory consumption of the new QMap implementation is pretty much the same as before. Performance of insertion and lookup has increased by 10-30%. iteration is slower, but still extremely fast and should not matter compared to the work usually done when iterating.

This directory contains autotests and benchmarks based on QTestlib. 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.
