A unauthorized user sents a update room subject message which is
rejected by the server. It responds with an error message which
is not picked up by the ChangeSubjectListener.
Mostly remove the helper utils. The server is required to present the
client with a consisent state of the block list and corresponding
modifications, so we should not end up with duplicate entires if we
don't check for them.
SMACK-731
Smack's previous entity caps implementation assumed that an entity lost
its entity caps feature as soon as a presence without caps from that
entity was received. But according to XEP-0115 § 8.4, this is a
perfectly normal optimization technique. We now reset the caps state
after an available presence becomes unavailable.
Also introduce PresenceEventListener, which is required for this
feature.
Also make Roster.preApprove() take a BareJid as argument.
Fixes SMACK-723.

Note the
<feature
xmlns='urn:xmpp:archive'><optional><default/></optional></feature>
which will cause the current parser implementation to parse it as
DiscoInfo Feature resulting in an Exception because some attributes are
missing.
This commit prevents this.
So that we can wrap the original exception within the
SmackException. It's not possible to wrap it into the IOException
because of the used min Android API level.
Check if serverSocket is null before calling isClosed(), as otherwise
the resulting NPE will cause an endless loop.
Thanks to Michael Grafl for reporting.
Fixes SMACK-707.
