Remove redundant link_updated code related to bookmarks
|Reported by:||solarissmoke||Owned by:|
The links table has a column called link_updated which used to be used to store the date the link last changed (using pingomatic to check for this).
The link update checking was removed from core some time ago, see #12437,  (also #4230, #4231). However there's still some code in wp-admin/bookmark.php and wp-admin/bookmark-template.php which uses link_updated as well as the links_recently_updated_time option. I guess the column in the database can't just be dropped because of back compat. But the code that uses it in core looks like it can.
