/**
* The purpose of this file is to provide an "esp_event_send_to_default_loop"
* function, which is used to forward legacy events (system_event_t) sent using
* esp_event_send, to the new default event loop (esp_event_post).
*
* For each of the events in system_event_id_t, we extract the event data from
* the corresponding system_event_info_t member, and forward that to
* esp_event_post function.
*
* Some macros are used to reduce the amount of boilerplate.
*
* Note that this function only needs to be included into the output file if
* the new default event loop is used. This function is in a separate file for
* readability reasons. In order to be linked if the contents of
* default_event_loop.c is linked, this file is #include-ed into default_event_loop.c.

* able to exit exactly at time of expiry as (1) blocking on internal mutexes is necessary for dispatching the unqueued
* event, and (2) during dispatch of the unqueued event there is no way to control the time occupied by handler code
* execution. The guaranteed time of exit is therefore the alloted time + amount of time required to dispatch
* the last unqueued event.
