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 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.
The inetAddressAndPort String is redundant since
a2743549b8, because we now construct the
InetSocketAddress earlier and can hence use it in the log statement.
The purpose of the "maybeCompressFeaturesReceived" synchronization
point is to wait for the stream features after authentication. This is
not really reflected by its name and furthermore its
checkIfSuccessOrWait() method was only invoked if compression was
enabled, but we always want to wait for the stream features after
authentication. Hence move the call before the isCompressionEnabled()
check and one layer up in the call stack.
Fixes SMACK-846.
using the default algorithm. Instead continue with 'null' as value of
the KeyManager[] array (kms). This makes the SSLContext.init() methods
to search the default security providers for implementations, which is
also OK.
This change is needed because it appears that on Android
KeyManagerFactory.getDefaultAlgorithm returns 'SunX509', which
subsequently results in

Note that this is possibly because the Secuurity Provider was
not (yet) intialized.
New stanzas sent directly after stream resumption might have been added
to unacknowledgedStanzas before the old unacknowledged stanzas
are resent. This caused new stanzas to be sent twice and later led
to a StreamManagementCounterError.

by calling String.equals() on the constant string and not on the
return value of parser.getName().
Also perform the access to 'parser' on a different LOC than
equals(). This should help debugging things like
