The functions checks if the item is lacking metadata altogether. If a video or audio file was uploaded prior to 3.6, it does not have any metadata. This tries to fix it. Implements locking via a transient to protect against this running in parallel with another request.
This is the minimum viable product for #26825, but leaving the ticket open unless this function needs to be called in other places.
See #26825.

* Consolidate the logic to avoid appending ellipsis if the entire string is shown.
* Show ellipsis after truncated filenames and post titles.

ID3 library. Also allows themes/plugins to add thumbnail support
to these media types. Think stuff like album art, movie covers, and
video freeze-frames.

The exceptions to this are update_post_meta() and add_post_meta() which are often used by plugins in POST handlers and will continue accepting slashed data for now.
Introduce wp_upate_post_meta() and wp_add_post_meta() as unslashed alternatives to update_post_meta() and add_post_meta(). These functions could become methods in WP_Post so don't use them too heavily yet.
Remove all escape() calls from wp_xmlrpc_server. Now that core expects unslashed data this is no longer needed.
Remove addslashes(), addslashes_gpc(), add_magic_quotes() calls on data being prepared for handoff to core functions that until now expected slashed data. Adding slashes in no longer necessary.
Introduce wp_unslash() and use to it remove slashes from GPCS data before using it in core API. Almost every instance of stripslashes() in core should now be wp_unslash(). In the future (a release or three) when GPCS is no longer slashed, wp_unslash() will stop stripping slashes and simply return what is passed. At this point wp_unslash() calls can be removed from core.
Introduce wp_slash() for slashing GPCS data. This will also turn into a noop once GPCS is no longer slashed. wp_slash() should almost never be used. It is mainly of use in unit tests.
Plugins should use wp_unslash() on data being passed to core API.
Plugins should no longer slash data being passed to core. So when you get_post() and then wp_insert_post() the post data from get_post() no longer needs addslashes(). Most plugins were not bothering with this. They will magically start doing the right thing. Unfortunately, those few souls who did it properly will now have to avoid calling addslashes() for 3.6 and newer.
Use wp_kses_post() and wp_kses_data(), which expect unslashed data, instead of wp_filter_post_kses() and wp_filter_kses(), which expect slashed data. Filters are no longer passed slashed data.
Remove many no longer necessary calls to $wpdb->escape() and esc_sql().
In wp_get_referer() and wp_get_original_referer(), return unslashed data.
Remove old stripslashes() calls from WP_Widget::update() handlers. These haven't been necessary since WP_Widget.
Switch several queries over to prepare().
Expect something to break.

We tried in vain -- a noble but ultimately failed effort -- to reduce the number of fields for attachments from four (title, caption, alt, description) to one (caption for images, title otherwise). Alternative text needed to stay for accessibility reasons, of course.
Eventually title returned due to heavy plugin reliance. Description is too used by too many plugins (often times incorrectly -- the caption is more likely the proper field), hence its less-than-triumphant return today.
Version 3.5 has tried to streamline media in a number of ways. Removing fields may have been too much at once, as it forced not only a user interface change, but a paradigm change as well.
Finally, on upload we populate the description field with IPTC/EXIF captions, rather than the caption field. See #22768, this should be fixed. For now, Description stays.
This commit also restores 'Title' attribute editing to the main tab of the Edit Image dialog. The "Title" field no longer populates title attributes for <img> tags by design (for accessibility and other purposes, see #18984). So, here is a more obvious 'workaround' for the tooltip community.
Finally, this:
* Cleans up the post.php attachment editor, including by showing a prettier form of the mime type.
* Enables plugins to specifically hide attachment_fields_to_edit from either post.php (where you can create meta boxes) or the modal (which you may not want to clutter), for compatibility reasons.
* Hides the 'Describe this file...' placeholder when a field is read-only in the modal.

Turn off multi selection uploads for mobile devices. Currently Plupload cannot upload multiple files in iOS Safari. Only the first file makes it to the queue.
Empty wp on unload to work around caching in iOS Safari.
