Append the messages up to the timestamp until, chronologically sorted, to messages. Keep track of the messages already sent and with each subsequent call to this method start with the first one not yet sent. Messages that have been sent can be deleted. When new data from the profiler arrives the information about the last sent message must be reset. Return the timestamp of the next message after until or -1 if there is no such message. The profiler service keeps a list of adapters, sorted by time of next message and keeps querying the first one to send messages up to the time of the second one. Like that we get chronologically sorted messages and can occasionally post the messages to exploit parallelism and save memory.
Implements QQmlAbstractProfilerAdapter.
