core: various changes and fixes to work with new storage and D-Bus bridge: - fixes coroutines handling in various places - fixes types which are not serialised by Tx DBus - XEP-0384: call storage methods in main thread in XEP: Python OMEMO's Promise use thread which prevent the use of AsyncIO loop. To work around that, callLater is used to launch storage method in main thread. This is a temporary workaround, as Python OMEMO should get rid of Promise implementation and threads soon.

ping: get response time of an XMPP entity
=========================================

``ping`` is more or less the equivalent of the command of the same name on most OSes, but
for XMPP. It send a `XEP-0199`_ PING and wait for the answer. When (and if) received, the
time to receive the answer is shown, else the time to receive the error message is shown.
This can be helpful to quickly test the connection with the server or a device.

If you need to get only the response time (without text around), you may use ``-d,
--delay-only``.

.. _XEP-0199: https://xmpp.org/extensions/xep-0199.html
