Retained memory available not checked at declaration

[felipepardo87587]

Thanks for this awesome work!

I am using most of the retained memory space in my program (Boron 2G). I discovered that the retained memory space limit is not checked when declaring the ConnectionEventData ConnectionEvents::connectionEventData buffer, it will use more retained memory space than is available, causing a hard panic when it tries to remove an event.

Fix: Make sure you have enough retained memory space (512 bytes is the default)
