update_get_available($refresh = FALSE)

Internal helper to try to get the update information from the cache if possible, and to refresh the cache when necessary.

In addition to checking the cache lifetime, this function also ensures that there are no .info files for enabled modules or themes that have a newer modification timestamp than the last time we checked for available update data. If any .info file was modified, it almost certainly means a new version of something was installed. Without fresh available update data, the logic in update_calculate_project_data() will be wrong and produce confusing, bogus results.
