Most in particular llevents.h, which comes along with the demand that the old events in llevent.h are put in a namespace LLOldEvents. Made all changes necessary to compile the rest of the code again (without changing the actual code: it's still using the old events). This patch also removes LLStopWhenHandled and LLStandardSignal from indra/llui/llnotifications.h because those are moved to llevents.h. That seems to be the only change to indra/llui/llnotifications.h that isn't floater related, so I left the rest of that file alone.
