Mobile SDK: Merging master into unstable

When app foreground we re-register with Salesforce (if we have a device token and logout was not requested).
On logout we unregister from Salesforce but:
- we no longer do that through a notification because the notification is sent after the logout has completed (and the un-register needs to be done while we are authenticated)
- we no longer use a sendAsynchronousRequest for un-register otherwise the delete (which would be queued) ends up being sent after the revoke refresh token
Registering with salesforce for notification after login (if the device was first registered with apple)
