Subject: mod_mam: Use user JID for stanza ID 'by' attribute

Use the user (or room) JID instead of the server JID for the 'by'
attribute of  and  tags.  That's what the
examples in XEP-0313 v0.2 and XEP-0359 v0.3.0 suggest.

From: Holger Weiss 
Date: Tue, 22 Nov 2016 19:25:20 +0100
Subject: Let ejabberd_sm mark copied messages

When multiple resources have the same (highest) priority, ejabberd_sm
dispatches messages addressed to the bare JID (or to an unavailable
resource) to each of these resources.  Such messages are now marked with
an 'sm_copy' flag for all but one of the resources.  This makes it
easier for other modules to identify those duplicates.

Resolves #1356.
