Volker Hilsheimer 924b97d6ab Fix QDateTimeEdit's handling of invalid time in dst gap
During a spring forward, a time-zone omits an hour. A QDateTime with
such an hour is invalid, but QDateTimeEdit's handling of this invalid
time was not done correctly.

With this fix, up/down changes of any field that would result in an
invalid date-time corrects the time to be valid, while leaving as
much as possible of the user-entered data unchanged. To do that, we
rely on QDateTime::toMSecsSinceEpoch to return a value even for such
an invalid time, which then can be used to construct a valid
QDateTime.

Edits that would result in an invalid hour are reverted to the
previous when pressing return, if correctionMode is
CorrectToPreviousValue. This change also implements support for
CorrectToNearestValue, which uses the same mechanism as when stepping
over an invalid time.

Include a test that verifies that the various interactions result
in a reasonable value. Since QDateTimeEdit does not respect the
timezone or timespec of the QDateTime it is initialized with, we
have to find the first hour of daylight saving time for a year
that we know works for most time zones. Failing that, we have to
skip the tests. Verified in a wide range of time zones.

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.
