[Libreoffice] ms import of ocx/userform controls

[Noel Power]

Hi there,
Be aware that in master regarding the  import of controls ( ole/ocx 
controls and userform controls ) , please be on the look out for any 
regressions in this area and let me know. Note: the import of older form 
controls is still handled in the escher import in filters, the hasn't 
changed. If you are interested in the background etc. read on, otherwise 
that's it

In an effort to reduce some confusing duplication I have started to try 
and 'retire' various parts of filter code that are duplicated. For some 
time now import of ole userform controls has been using the new filter 
code in oox but the import of those same controls ( when not appearing 
in a userform ) has been using the old filter code in 
filters/source/msfilter/msocximex.cxx.

The integration is still quiet ugly while this transition is ongoing, 
regarding ole/ocx controls the export of these is still handled in the 
old filter ( I didn't investigate yet what export capability ( if any ) 
is in the new filter) it appears this is only relevant for writer. 
Additionally there were some controls that were handled in the old 
filter that were not in the new one ( I ported those ). The changes ( 
rather more than I expected ) are below

note: a similar situation also exists for import of vba projects and 
code, there is a new vbaproject filter in oox but still in some places 
the old filter ( at least afaik for impress ) is used. It would be 
really nice to get rid of that old code too.

thanks,

Noel
