Provide additional information in user-related hooks

[ketsugi]

Giving a couple of hooks some extra information to pass to plugins. Because of the way the WP plugin API is implemented, giving these hooks the ability to pass more parameters does not actually break any existing plugins.

first two patches aren't providing data that couldn't be fetched using the existing passed data.

Let's not expand on a deprecated hook, i.e. retreive_password.

Please can you leave a comment explaining why you've closed the ticket.

All open tickets should have a milestone.

Is this still needed? Seems like the extra info can be accessed through the global user object. Closing as wontfix, feel free to reopen if needed.
