[REVIEW 3-5] fdo#37044 crash on mac with transliteration

This is one of our oldest bugs, looking at the backtraces I'm fairly
sure this has to be triggered by having two differently-layout structs
called TransliterationChgData, one in sw and one in editeng, seeing as
the crash is happening in editeng on calling
TransliterationChgData::push_back in sw and it has no place going
anywhere near editeng.

So simply renaming the two structs to be different would likely fix it, 
http://cgit.freedesktop.org/libreoffice/core/commit/?id=7080d629c82422a419d38051536c7711f8abe53e
attached backport to 3-5 to fix minor conflicts.
