 #!CommitTicketReference repository="" revision="43540"
 Cron: Add hooks and a function to allow hijacking cron implementation.

 This allows sites with a large cron option or a custom cron implementation
 to hijack the cron option to store cron data using custom functionality.

 `wp_get_scheduled_event()` is new function to retrieve the event object
 for a given event based on the hook name, arguments and timestamp. If no
 timestamp is specified the next occurence is returned.

 Preflight filters are added to all functions that read from or modify the
 cron option: `pre_schedule_event`, `pre_reschedule_event`,
 `pre_unschedule_event`, `pre_clear_scheduled_hook`, `pre_unschedule_hook`,
 `pre_get_scheduled_event` and `pre_next_scheduled`.

 Additionally, the post scheduling hooks `next_scheduled` and
 `get_schedule` to allow plugins to modify an event after retrieving it
 from WordPress.

 Props rmccue, DavidAnderson, ethitter, peterwilsoncc.
 Fixes #32656.
