* Implementation of hook_requirements().

* @return
* An array describing the status of the site regarding available updates.
* If there is no update data, only one record will be returned, indicating
* that the status of core can't be determined. If data is available, there
* will be two records: one for core, and another for all of contrib
* (assuming there are any contributed modules or themes enabled on the
* site). In addition to the fields expected by hook_requirements ('value',
* 'severity', and optionally 'description'), this array will contain a
* 'reason' attribute, which is an integer constant to indicate why the
* given status is being returned (UPDATE_NOT_SECURE, UPDATE_NOT_CURRENT, or
* UPDATE_UNKNOWN). This is used for generating the appropriate e-mail
* notification messages during update_cron(), and might be useful for other
* modules that invoke update_requirements() to find out if the site is up
* to date or not.
*
* @see _update_message_text()
* @see _update_cron_notify()
