This commit adds the modules smack-omemo and smack-omemo-signal.
smack-omemo is licensed under the Apache license like the rest of the smack project.
smack-omemo-signal on the other hand is licensed under the GPLv3.
Due to the fact, that smack-omemo is not of much use without smack-omemo-signal,
the OMEMO feature can currently only be used by GPLv3 compatible software.
This may change in the future, when a more permissively licensed module becomes available.
Fixes SMACK-743.
In case the server provided nonce contained one or more equals
characters ("=") the part.split("=") call would return more then the
expected two key/value parts. Hence we simply use part.split("=", 2).
Also made the unit test check for this case.
Fixes SMACK-755
This caused the WaitForClosingStreamElementTest integration test to
fail, because the last presences stanzas, which are send after done()
in the writer thread would return true, are not added to the
unacknowledgedStanzas queue.
The result was:
