remove xmpp support

I've long considered the XMPP support in git-annex a wart.
It's nice to remove it.

(This also removes the NetMessager, which was only used for XMPP, and the
daemonstatus's desynced list (likewise).)

Existing XMPP remotes should be ignored by git-annex.

-XMPP (Jabber) is used by the [[assistant]] as a git remote. This is,
-technically not a git-annex special remote (large files are not transferred
-over XMPP; only git commits are sent).
-
-Typically XMPP will be set up using the web app, but here's how a manual
-set up could be accomplished:
-
-1. xmpp login credentials need to be stored in `.git/annex/creds/xmpp`.
-   Obviously this file should be mode 600. An example file:
-
-	XMPPCreds {xmppUsername = "joeyhess", xmppPassword = "xxxx", xmppHostname = "xmpp.l.google.com.", xmppPort = 5222, xmppJID = "joeyhess@gmail.com"}
-
-2. A git remote is created using a special url, of the form `xmpp::user@host`
-   For the above example, it would be `url = xmpp::joeyhess@gmail.com`
-
-3. The uuid of one of the other clients using XMPP should be configured
-   using the `annex.uuid` setting, the same as is set up for other remotes.
-
-With the above configuration, the [[assistant]] will use xmpp remotes much as
-any other git remote. Since XMPP requires a client that is continually running
-to see incoming pushes, the XMPP remote cannot be used with git at the
-command line.

+XMPP (Jabber) used to be able to be used by the [[assistant]] as a git remote.
+This never worked very well, and it was not entirely secure, since the XMPP
+server saw the contents of git pushes without encryption. So, XMPP support
+has been removed.
