Subject: [PATCH 3/6] services: prosody: Adapt to Prosody 0.10.0.

From: Clément Lassieur <[email-masked]>
Date: Fri, 24 Nov 2017 17:52:24 +0100

* doc/guix.texi (Messaging Services): Add "mam" as a module example.  Document
'prosodyctl check'.  Replace 'prosodyctl cert request' with 'prosodyctl cert
import'.  Regenerate it.
* gnu/services/messaging.scm (serialize-module-list): Remove "posix" from the
default modules list because it is now automatically loaded.
(ssl-configuration)[key, certificate]: Remove them because they are now
automatically located.  Fix their docstrings.
(%default-modules-enabled): Add "carbons" and "blocklist".
(prosody-configuration)[certificates]: Set default directory from which
certificates/keys will be automatically located.
