fdo#46808 - [Easy Hack] Adapt UNO services to new-style

[Noel Grandin]

Hi

Great explanation.

In order to limit the knock-on effect from my change (I'm already up to 
about 12 files, and it just keeps spreading), I need to be able to 
convert an XComponentContext back into a XMultiServiceFactory.

How do I do that?

Thanks, Noel Grandin
