Merge branch '4.7' of scm.dev.nokia.troll.no:qt/oslo-staging-2 into 4.7-integration

* '4.7' of scm.dev.nokia.troll.no:qt/oslo-staging-2:
  Used aligned load and store when possible for the blending of ARGB32
  Windows mobile: hide [X] button in task bar on unmaximize
  Windows mobile: the [X] button in the taskbar minimizes the widget
  Windows mobile: show the [X] button in the taskbar when maximizing
  unused struct DIBINFO removed from qguifunctions_wince.cpp
  Fixes the Oracle invalid date bug when date is greater or equal to 2800
