Commit Message

trigger: fix NULL dereference and memory leak

Using LuaC API, one can create a callable number - it will be callable
and at the same time lua_topointer will return NULL if such number will
be passed. And function luaT_event_reset_trigger_with_flags relies on the
fact that lua_topointer cannot return NULL if it is called with a
callable object. The assumption is wrong, so let's rewrite the function
without relying on it.

NB: if you are using old trigger API with such exotic handlers, you can
have only one such trigger in an event - it will occupy name '0x0'.

Closes #9287
