Because of the condition "c >= 32", Smack would possible return a
c-nonce containing ASCII whitespace characters (32d, 0x20), which are
not allowed in the c-nonce as per RFC 5802.
This commit applies the correct condition: "c > 32".
Fixes SMACK-735.
Also don't override eventually send presences on
updateLocalEntityCaps(), instead save the last sent Presence stanza and
re-send that stanza.

as otherwhise SynchronizationPoint may report NoResponseException when
there was in fact a success or failure reported in case there are
multiple threads waiting for the condition.
to prevent a thread from not being notified about a change of the state
of the SynchronizationPoint.
If two threads are waiting for a change, which could happen e.g. because
of a connectivity change and one thread does instantShutdown() while the
other handles connectionClosedOnError(), then only one thread, usually
the one handling connectionClosedOnError(), would be notified and
resumed.
Fixes SMACK-652.
Until now the reconnection used a fixed policy using random
increasing delay as the number of attempts grows. Even if
that policy is still the default one, it is now possible to
select a fixed delay policy that always waits a fixed amount
of time before trying to reconnect
With bb8dcc9874 the concept if IQ request
handlers was introduced in Smack. This doesn't allow packet/stanza
collectors/listeners to filter for incoming IQ requests. Unfortunately
the file transfer code relied on this being able, so it broke with the
change.
There were two places where the file transfer code was listening for
incoming IQ requests:
- InitationListener(s)
- Negotiator(s)
With this change, we let the InitiationListener signal the existence of
an incoming initation request, send by an IQ of type 'set', using the
newly created EventManager utility.
The negotiator waits for those events to arrive and proceedes as it would
have done when the packet collector was used.
the combination with concurrencyLevel and LinkedBlockingQueue never
worked as intented. The idea was that the cachedExecutorService would
spawn new threads until maximumPoolSize (=concurrencyLevel) is reached,
and then start queing the Runnables.
But this was not the case, since ThreadPoolExecutor does not take into
consideration if the worker threads is busy, i.e. executing a Runnable,
or idle, i.e. waiting for a Runnable.
This means that if a busy Worker would execute a Runnable, which would
block, because it's waiting for an event (e.g. an incoming IQ
request), then the handling of those incoming IQ request would be
queued by ThreadPoolExecutor, because no fewer threads then corePoolSize
are running and the task can be queued (since the LinkedBlockingQueue is
unbounded).
Using the term 'enabled' was a terriable choice from a security
perspective, as it gives the user the impression that the security is
"enabled". In fact this setting is only slightly better then
"disabled".
Make that fact clear in the javadoc too.
