feilongliu 0b0cb6f1a2 Fix segfalut in ~DBWithTTLImpl() when called after Close() (#5485) ... Summary: ~DBWithTTLImpl() fails after calling Close() function (will invoke the Close() function of DBImpl), because the Close() function deletes default_cf_handle_ which is used in the GetOptions() function called in ~DBWithTTLImpl(), hence lead to segfault. Fix by creating a Close() function for the DBWithTTLImpl class and do the close and the work originally in ~DBWithTTLImpl(). If the Close() function is not called, it will be called in the ~DBWithTTLImpl() function.
