 {{{
 #!CommitTicketReference repository="" revision="58128"
 Upgrade/Install: Automatically roll back to the previous version when an
 automatic plugin update results in a fatal error on the front end of the
 site.

 This builds on the temporary backup system introduced in 6.3 to allow
 automatic updates to benefit from fatal error protection. A loopback
 request is performed to the home page of the site and the plugin is rolled
 back to its backed up version if a fatal error is observed.

 For debugging and observability during beta, this change includes several
 calls to `error_log()` during the upgrade and rollback stages. These calls
 can be removed or placed behind a flag once we're ready for RC1.
