libreoffice/xmlsecurity/source/helper/xmlsignaturehelper.cxx
Noel Grandin 1dedb15b17 fdo#46808, Adapt xml::crypto::SEInitializer UNO service to new style 
Also create an NSSInitializer service IDL and split it's interfaces
out from SEInitializer.
It looks like this was the intention all along, but someone
took a shortcut.
