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.
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.
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.
