Since notify() is a rather expensive operation, we should only invoke
it once. Especially since some servers include 110 in all self
presences, not just the initially reflected one on MUC join.
The change in 52a49769f9 ("[muc] Check for self-presence first in
presence listener") caused all self-presences (MUC user status 110) to
be ignored in the further processing chain eventually invoking
checkRoleModifications() and checkAffiliationModifications(). However,
some servers (e.g., ejabberd) include 110 not only in the initial
presence but in all following, and we ant to process these.
Fixes SMACK-918
Fixes: 52a49769f9
Calling userHasLeft before sending the leave presence may result in
invalid state as the MUC presence lister may modify the MUCs local
state, e.g., occupantsMap, conurrently with the leave operation.
If we reset it after the leave presence was send and acknowledged,
then this can not happen as the server will not longer send any MUC
related presences to us.
Also fixes SMACK-914. In theory 52a49769f9 ("[muc] Check for
self-presence first in presence listener") alone would fix SMACK-914,
but this also fixes it indepentendly of 52a49769f9. Both commits are
sensible, so both are applied.
Refactored using
find . -type f -name "*.java" |\
xargs sed -i -E |\
's/\.createStanzaCollectorAndSend\((\w+)\)\.nextResultOrThrow\(\);/.sendIqRequestAndWaitForResponse(\1);/'
and some manual refactoring.
This also resulted in a refactoring of the Providers and parsing
Exceptions. NumberFormatException and ParseException can now be thrown
directly, the wrapping in a SmackParsingException is down at a higher
layer, i.e. in AbstractProvider.
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.
Apply builder pattern to form fields and replace getVariable() with
getFieldName(). Refer to the field name as "field name" instead of
"variable" everyone, just as XEP-0004 does.
Improve the high-level form API: introduce FilledForm and FillableForm
which perform stronger validation and consistency checks.
Also add FormFieldRegistry to enable processing of 'submit' forms
where the form field types are omitted.
Smack also now does omit the form field type declaration on 'submit'
type forms, as it is allowed by XEP-0004.
The previous site where the callback was invoked was only reached if
there was also a user status on the unvailable presence. But those are
not part of unavilable presences upon room destruction.
Fixes SMACK-888.
There is no need to duplicate that code. Also ensure that
userHasLeft() is invoked *before* the listeners are invoked, so that
e.g. isJoined() returns false in the listeners.
Returning a generic would allow for
List<ExtensionElement> list = stanza.getExtension("foo", "bar");
to compile (Note the we are calling getExtension(), not
getExtension*s*()).
Users are encouraged to use the type safe getExtension(Class<? extends
ExtensionElement) variant instead.
Fixes SMACK-825.
Those, relatively new, listeners guarantee that the individual
listeners are not invoked in concurrently while preserving the
order. Exactly what MultiUserChat previously did with AsyncButOrdered,
which is now no longer needed and hence can be removed.
