Existing API tep_list_events() is not thread safe, it uses the internal array sort_events to keep cache of the sorted events and reuses it. This patch implements a new API, tep_list_events_copy(), which allocates new sorted array each time it is called. It could be used when a sorted events functionality is needed in thread safe use cases. It is up to the caller to free the array.
