[bug#29425] Prosody patches

[Clément Lassieur]

Patches 1 to 3 are related to the Prosody 0.10 update.  I'll push them
with Rutger's patch
(https://lists.gnu.org/archive/html/guix-patches/2017-11/txtZP9gLpmpSr.txt).

Patches 4 to 6 are unrelated improvements to the service.

[bug#29425] [PATCH 3/6] services: prosody: Adapt to Prosody 0.10.0.

[Clément Lassieur]

* 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.

Maybe we could write:

  (define (lua-bitop lua)
    (package
      …))

  (define lua5.1-bitop (lua-bitop lua-5.1))
  (define lua5.2-bitop (lua-bitop lua-5.2))

?

If not, this patch LGTM.

Thank you,

LGTM.

I suppose the Prosody update should be applied before this one, right?

Okay! Please add a comment about why we need all these different
lua-bitops :)

Thank you for the review!  I'll put a comment on the patch that updates
Prosody to 0.10 saying that Lua 5.1 is still recommended for production
usage.
