/**
* This function handles the complex flow of signing users in, and either creating,
* linking (or not linking) accounts depending on if the user is currently logged
* in, if they have account already and the authentication mechanism they are using.
*
* It prevents insecure behaviour, such as linking OAuth accounts unless a user is
* signed in and authenticated with an existing valid account.
*
* All verification (e.g. OAuth flows or email address verificaiton flows) are
* done prior to this handler being called to avoid additonal complexity in this
* handler.
