Port wincred keyring to PurpleCredentialManager

* Inline PURPLE_PLUGIN_INIT in wincred.
* Add skeleton of wincred PurpleCredentialProvider object.
* Implement password reading.
* Implement wincred password writing.
* Implement wincred password clearing.
* Autoload wincred keyring plugin.
* Cleanup formatting.

Testing Done:
Added XMPP account, saved password, disabled and re-enabled account which kept the password. Restarted Pidgin and password was still saved. Removed XMPP account, and password was deleted from Credential Manager.

I'm not sure that the password needs to be converted from UTF-8 to "Unicode", as I did not test modifying the password in Credential Manager.

Bugs closed: PIDGIN-17489

/**
* PurpleProtocolChatInterface:
* @info: Returns a list of #PurpleProtocolChatEntry structs, which represent
* information required by the protocol to join a chat. libpurple will
* call join_chat along with the information filled by the user.
* @info_defaults: Returns a hashtable which maps #PurpleProtocolChatEntry
* struct identifiers to default options as strings based on
* @chat_name. The resulting hashtable should be created with
* #g_hash_table_new_full(#g_str_hash, #g_str_equal, %NULL,
* #g_free). Use @get_name if you instead need to extract a chat
* name from a hashtable.
* @join: Called when the user requests joining a chat. Should arrange for
* purple_serv_got_joined_chat() to be called.
* @reject: Called when the user refuses a chat invitation.
* @get_name: Returns a chat name based on the information in components. Use
* @info_defaults if you instead need to generate a hashtable from a
* chat name.
* @invite: Invite a user to join a chat.
* @leave: Called when the user requests leaving a chat.
* @send: Send a message to a chat.
* @get_user_real_name: Gets the real name of a participant in a chat. For
* example, on XMPP this turns a chat room nick
* <literal>foo</literal> into
* <literal>room\@server/foo</literal>.
* @set_topic: Called to set the topic for the given chat.
*
* The protocol chat interface.
*
* This interface provides callbacks needed by protocols that implement chats.
