This code branch is responsible for running all autoupdates, including plugins and themes - which should run regardless of if there's a core autoupdate available. This revert does not revert the `$timeout` changes, as these should still use cached data if it's available. Ideally this should be decoupled from the core update check to allow background updates to operate even when the core update check is disabled or running more often than twice daily. Merges [42653] to the 4.9 branch. Fixes #43103, #43235. Built from https://develop.svn.wordpress.org/branches/4.9@42654 git-svn-id: http://core.svn.wordpress.org/branches/4.9@42483 1a063a9b-81f0-0310-95a4-ce76da25c4cd
