Ritt Konstantin 9f865df5d1 optimize QList::removeAll()
a) don't detach until an occurrence found
b) don't memmove every time an occurrence found
c) truncate quickly )

well, numbers are better than words:
before:
RESULT : tst_QList::removeAll_primitive():
     2,617,902 CPU ticks per iteration (total: 261,790,171, iterations: 100)
RESULT : tst_QList::removeAll_movable():
     2,547,540 CPU ticks per iteration (total: 254,753,960, iterations: 100)
RESULT : tst_QList::removeAll_complex():
     16,852,099 CPU ticks per iteration (total: 1,685,209,906, iterations: 100)

after:
RESULT : tst_QList::removeAll_primitive():
     73,520 CPU ticks per iteration (total: 73,520,442, iterations: 1000)
RESULT : tst_QList::removeAll_movable():

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.
