function _update_process_info_list

Populates an array of project data.

This iterates over a list of the installed modules or themes and groups them by project and status. A few parts of this function assume that enabled modules and themes are always processed first, and if disabled modules or themes are being processed (there is a setting to control if disabled code should be included or not in the 'Available updates' report), those are only processed after $projects has been populated with information about the enabled code. Modules and themes set as hidden are always ignored. This function also records the latest change time on the .info files for each module or theme, which is important data which is used when deciding if the cached available update data should be invalidated.

Parameters

$projects: Reference to the array of project data of what's installed on this site.

$list: Array of data to process to add the relevant info to the $projects array.

$project_type: The kind of data in the list. Can be 'module' or 'theme'.

$status: Boolean that controls what status (enabled or disabled) to process out of the $list and add to the $projects array.
