The method lookupHostAddress() returns null in case of an error, hence
we need to test if the returned value is null prior adding the endpoint.
Should fix the following NPE:
java.lang.NullPointerException:

This fixes an inconsistent representation of a 'no error' representation, that
causes a file transfer in which not enough bytes were transferred to _not_ be
marked as having a problem.
This prevents a race condition of enter() with the presence listern by
waiting until all presences have been processed.

To increase readability, and with that maintainability, we rename
'presence' to 'reflectedSelfPresence' in MultiUserChat.enter(), to
make it clear what kind of presence this variable holds.
Also mark the variable as final.
Do net put an ack to the queue if it has already been shutdown. Some
servers, like ejabberd, like to request an ack even after we have send
a stream close (and hance the queue was shutdown). If we would not
check here, then the ack would dangle around in the queue, and be send
on the next re-connection attempt even before the stream open.
See the following trace of the MUC bookmarks integration test. The
fact that it is a MUC test does not matter, but this test does
disconnect the connection and reconnect it. Not how the server,
ejabberd in this case, requests an SM ack by sending an <r/> even
though we already send the </stream:stream>:

Instead of breaking in case the SSLEngine signals NEED_WRAP, which
leads to an endless loop while holding the
channelSelectedCallbackLock, we have to return, so that the
asynchronously invoked callback can aquire it, and do its work.
Smack currently does unnecessary escaping of XML text, where it
escapes e.g. '"' to '"'. This bloats the stanza size, especially
if JSON payloads are involved.
Fixes SMACK-892 (although there are probably still places where
XmlStringBuilder.escape() is used when XmlStringBuild.text() could
have been used).
This means that users get now exceptions with helpful error messages
instead of the dreaded ClassCastException, like
java.lang.ClassCastException: org.jivesoftware.smack.packet.StandardExtensionElement cannot be cast to org.jivesoftware.smackx.mam.element.MamElements$MamResultExtension
at
when StanzaView.getExtension(Class) is used to retrieve the extension.
