tdf#125397: Fixes for threads and SolarMutex on iOS
We need to call SfxApplication::GetOrCreate() in lo_initialize() now. Otherwise we will crash in sfx2. No idea why it worked earlier. I think we want to avoid the "VCLXToolkit VCL main thread" ever running in the iOS app. I don't think we had it running earlier, but now for some reason it got started when creating a document from a template, and that seemed to cause a hang. Also, when creating a document from a template, lo_initialize() is called from the app's real main thread (the one that the process starts in). In that case we do want to release the SolarMutex after InitVCL() if this was the first time we called InitVCL(). Awful crack. Not really sure I fully understand all that is going on, but this change does seem to fix recent problems... All this thread and SolarMutex stuff is so incredibly fragile.
