Helper: append a cell statistics string to event_parts, prefixed with key=. Statistics consist of comma-separated key:value pairs with lower-case command strings as keys and cell numbers or total waiting times as values. A key:value pair is included if the entry in include_if_non_zero is not zero, but with the (possibly zero) entry from number_to_include. Both arrays are expected to have a length of CELL_COMMAND_MAX_ + 1. If no entry in include_if_non_zero is positive, no string will be added to event_parts.

Helper: inserts an event on the list of events queued to be sent to one or more controllers, and schedules the events to be flushed if needed.
This function takes ownership of msg, and may free it.
We queue these events rather than send them immediately in order to break the dependency in our callgraph from code that generates events for the controller, and the network layer at large. Otherwise, nearly every interesting part of Tor would potentially call every other interesting part of Tor.
