…_impl &` Before this PR, its implementation had code paths for `nullptr` argument, but it's never `nullptr` at any of the call sites. Originally, this method was added in intel#7531 and was called with `nullptr` argument from some fusion code (at least), but it doesn't seem to be the case anymore (and fusion support has been removed from the project). Also, for some reason it was accepting `std::shared_ptr<event_impl>` by value and not by reference (no idea why), and the name was `NewEvent` without any comments/documentation. The former is irrelevant after this change, and for the latter I'm changing the name to a neutral "Event". If someone has a better understanding, please let me know.

Known non-null due to dereference at line 136. Closing } at line 145 is from the lock guard scope, so we do go through line 135 before making this call.

This delete is just bizarre, the ownership model is totally unclear here. Irrelevant to this PR though.
