// Entries Loading managment
//-------------------------------------------------
//	For each type of events, a part of entries are loaded with a minimal count (=mLastEntriesStep). Like that, we have from 0 to 3*mLastEntriesStep events.
//	We store them in a list that will be sorted from oldest to newest.
//	From the oldest, we loop till having at least one type of event or if we hit the minimum limit.
//		As it was a request for each events, we ensure to get all available events after it.
//	Notations : M0 is the first Message event; N0, the first EventLog; C0, the first Call event. After '|', there are mLastEntriesStep events.
// Available cases examples :
//	'M0...N0....|...C0....' =>  '|...C0....'
//	'M0C0N0|...' == 'C0N0|...' == '|N0....C0....' == '|N0....C0....' == '|.......'  We suppose that we got all available events for the current scope.
//	'N0...M0....C0...|...' => '|C0...'
//
//	-------------------
//
//	When requesting more entries, we count the number of events we got. Each numbers represent the index from what we can retrieve next events from linphone database.
//	Like that, we avoid to load all database. A bad point is about loading call events : There are no range to retrieve and we don't want to load the entire database. So for this case, this is not fully optimized (optimization is only about GUI and connections)
//
//	Request more entries are coming from GUI. Like that, we don't have to manage if events are filtered or not (only messages, call, events).
