Adjust acceptance tests for the fix to LP: #1198000
1. Always set frame extents before updating the frame
2. Added COMPIZ_NO_CONFIGURE_BUFFER_LOCKS so that we don't have to deal
with the delayed configure requests logic in the tests where it
does not help
3. Split restoredDecorationSize in to restoredDecorationBorderSize
and restoredDecorationInputSize so that we can measure the size of
the decoration both in terms of its visible and invisible border
4. Wait for the default decoration properly
5. Capture the initial geometry of the window with and without decorations
when the window gets its first decoration. Use these values to calculate
the size changes in the window from then on instead of its creation
values
6. Just flag when the window was first decorated in setWindowFrameExtents
rather than checking if it is mapped. We only want to not resize
the window once.
