Changing the height of the footer frame (i.e. by creating a new line in
it) didn't update the page margins and broke the rendering of the
header/footer decorators. To avoid that, redraw the whole page when the
SwFooterFrm is invalid.

 - make sure it doesn't replace character properties of textbody inside cells

This fixes fdo#32719.

To avoid making it appear to be a derived interface of XPropertySet
when it's not.

This is to preserve ABI backward compatibility with cppu::OPropertySetHelper.

NOTE: This needs to be double-checked by an expert.  I'm modifying
a symbol that's defined in the UDK_3_0_0 section.  I'm not really
sure if this will cause any ABI breakages for either the core code
or extensions.

ScVbaControl doesn't have any container instance to pass to the
old method.

Sometimes broadcasting changes to the property set on every new
value insertion makes no sense especially during import.  Turning
that off also improves performance especially when inserting millions
of property values.

This removes O(n^2) from the process of querying the code pages for
form elements.

With this, 3.81 sec -> 1.2 sec.
