#29891: Display error message when Media Library upload fails

----------------------------+-----------------------------
 Currently, when an upload fails in the media library, the following
 message is displayed:

   An error occurred in the upload. Please try again later.

 Behind the scenes, more useful error messages are set into the failure
 response, but they're not being exposed to the user. For example, `/wp-
 admin/includes/ms.php` returns error messages related to unavailable disk
 space, but only the message above is displayed.

 Attached is a patch to display the error response to the user alongside
 the generic error message above.
