Joe McGill 7710b3d3ec Media: Improve image filetype checking. ... This adds a new function `wp_get_image_mime()` which is used by `wp_check_filetype_and_ext()` to validate image files using `exif_imagetype()` if available instead of `getimagesize()`. `getimagesize()` is less performant than `exif_imagetype()` and is dependent on GD. If `exif_imagetype()` is not available, it falls back to `getimagesize()` as before. If `wp_check_filetype_and_ext()` can't validate the filetype, we now return `false` for ext/MIME values. See #11946. git-svn-id: https://develop.svn.wordpress.org/trunk@39831 602fd350-edb4-49c9-b593-d223f7449a82		2017-01-11 13:07:54 +00:00
