Deprecate Blogger XML-RPC Methods

[maxcutler]

The XML-RPC API supports the legacy Blogger API methods, but these methods have apparently not been very well tested or maintained.

Given that the wp.* XML-RPC namespace now covers everything that the Blogger API does, I suggest the blogger methods be officially deprecated with an eye towards removing them in a future version.

At the very least, the MetaWeblog API should be used by clients instead, as it was explicitly designed to enhance and supersede the Blogger API.

For reference, I've attempted to document the current implementation: ​http://codex.wordpress.org/User:Maxcutler/XML-RPC_Blogger_API

Looking through the code, there are places where the wp.* functions call the blogger.* functions. For instance, class-wp-xmlrpc-server.php (line 466) function wp_getUsersBlogs calls to "blogger_getUsersBlogs."

To re-write this seems like a large code change for an entire system that is antiquated and may soon be replaced. If the decision is to remove them, they should be deprecated first so that these functions don't break existing sites that reply on these calls.

Moving code around is totally fine so that isn't really an issue. And removing stuff can be easily put into a plugin.

This still needs a patch to be considered.
