#10658: XMLRPC failure string should convey disabled status for GET requests, too

 Currently if you issues a plain GET request (e.g. by trying to load an
 xmlrpc.php URL in a browser), you get the error string provided by wp-
 includes/class-IXR.php:

 XML-RPC server accepts POST requests only.

 This is not indicative of any configuration problem when XMLRPC has not
 been enabled for the blog.  Compare to wp-app.php which, in a comparable
 situation, at least indicates the configuration problem:

 AtomPub services are disabled on this blog.  An admin user can enable them
 at http://192.168.1.20/wptrunk/wp-admin/options-writing.php

 The attached patch changes xmlrpc.php so that it will provide the same
 type of verbose message as wp-app.php does, allowing clients to see
 immediately upon trying to access the xmlrpc endpoint URL, that service is
 disabled:

 XML-RPC services are disabled on this blog.  An admin user can enable them
 at http://192.168.1.20/wptrunk/wp-admin/options-writing.php

 I think this will have a positive impact on providing support e.g. to
 users of applications that depend on the API. It's a shortcut when
 debugging functionality to type in the xmlrpc URL into the browser to make
 sure it's configured correctly, and not spewing any errors.

 While I was at it I factored the generation of the string for disabled
 XMLRPC into a new method errorStringForDisabledXMLRPC().
