plugin XEP-0198: retrieve missing messages + send buffered ones on hot reconnection: Missing one2one messages are now retrieved with MAM on hot reconnection, and buffered ones (which have most probably not been received by the server) are resent at the end of the reconnection workflow. IQ results are not re-sent on hot reconnection, as they don't make sense anymore with a new session. fix 330
