dispatcher: Add a more safe dispatcher_send_message_custom version

Browse Source 
Use a template to wrap the other dispatcher_send_message_custom
avoiding having to pass a void* opaque and extract payload size
from passed type.
Will be used more by next commit when Dispatchers are turned into
C++.
