9b4815e3c8 ESP Event: multiple registrations to one event
* It's possible now to register the same handler
  several times to one specific event, using
  a dynamic handle object.

4c97906fc8 esp_event: fix crash when unregistering a handler instance in itself
When a handler instance is the last one in the list und unregisters
itself, the handler iterator will be invalidated by entering free'd
memory. Same applies for event base and id, if they become empty.

f21b8bbf55 esp_event: fix issue with post data preparation
Fixes an issue with post instance data preparation. Currently, there is
no way to check if event data has really been set during handler
execution preparation. When data is not allocated from the heap, user
could have passed 0x0 which can lead to failed checks.

This also implements using the already allocated data memory for posting
events from non-ISR functions when data size is less than the capacity.
