We assume that the connection is good even if there was no ping
result but a stanzas within the ping interval.
In some case we have produced so much load, that the ping result
was not delivered in time because so many other packets were
delivered before.
If a stream resume fails, smack will re-send all queued stanzas after a
reconnect. However, it does not make sense to re-send them:
* IQs / IQ responses have probably timed out
* MUC messages and PMs will be rejected as you haven't rejoined yet
* regular messages should be amended with a <delay> element
This patch adds a StanzaDroppedListener interface to the
XMPPTCPConnection. If at least one StanzaDroppedListener is provided,
all queued messages will be drained into the StanzaDroppedListener(s).
Otherwise, the original behavior of attempting to transmit them will be
followed.

To prevent timeouts when joining very large MUCs we now reset the
self-presence collector's timeout for every other (occupant) presence
we receive.
Fixes SMACK-859.
to clean up the state build up by connect().
Related to SMACK-855 there is the possiblitiy of a stray (writer)
thread if, for example, tlsHandled.checkifSuccessOrWaitorThrow() in
XMPPTCPConnection.connectInternal() throws. This commit should prevent
that.
