[xmpp] 3921bis: delivery of messages addressed to bare JIDs

[Peter Saint-Andre <stpeter at stpeter.im>]

Currently some XMPP services broadcast messages addressed to a bare JID
instead of delivering those messages only to the highest-priority
resource(s). The highest-priority rule is a legacy of the original
jabberd 1.x codebase and I don't see a strong reason to forbid other
message delivery styles. Therefore I propose a change to Section 8.3.1.1
of 3921bis.

The relevant text in -03 reads:

   For a message stanza of type "chat" or "normal", the server SHOULD
   deliver the stanza to the highest-priority available resource.

(Followed by text about delivery ties.)

I propose the following text for -04:

   For a message stanza of type "chat" or "normal", the server MUST
   either (a) deliver the stanza to all available resources or (b)
   deliver the stanza to the highest-priority available resource.

(Again followed by text about delivery ties in case (b).)

Thoughts?

Peter
