Nicolas Fella 74c59f8a23 QIcuTimeZonePrivate constructor: save iteration over all zone IDs
ICU returns a "valid" representation of GMT when given an unrecognised
ID, so QTZ's constructor has been checking the ID is available before
passing it to the backend constructor. That availability check was
done by generating the list of available IDs to see if the given ID
was in it; this is very inefficient. Furthermore, the QTZ constructor
was also checking availability, to work round the same issue in only
this one backend, making the check redundant.

So overide isTimeZoneIdAvailable() in the ICU backend, calling
ucal_getCanonicalTimeZoneID(), which answers the question directly;
and drop the duplicate check in the QTZ constructor. Expand a test to
verify an invalid name is rejected.

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.
