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.

When upgrading to `utf8mb4`, `TEXT` fields will be upgraded to `MEDIUMTEXT` (and likewise for all other `*TEXT` and `*BLOB` fields). This is to allow for the additional space requirements of `utf8mb4`.
On the subsequent upgrade, `dbDelta()` would try and downgrade the fields to their original size again. At best, this it a waste of time, at worst, this could truncate any data larger than the original size. There's no harm in leaving them at their new size, so let's do that.
This also fixes a typo in the `dbDelta()` tests.

When the post being embedded is from the same site, there's no reason to do an HTTP request for it. The data can be fetched directly using `get_oembed_response_data()`.

The codex says that taxonomy names "should only contain lowercase letters and the underscore character", but that's not enforced. It's too late to enforce it, since some plugins haven't been following it and the official phpdoc doesn't mention this restriction.

We are escaping arguments, not commands, so we'd better use the semantically correct function, even though they are similar.

When the browser test for diversity emoji was added in [36160], it included a workaround for Chrome not being able to compare Uint8ClampedArray objects directly, by converting them to a string. Unfortunately, Safari doesn't support the Uint8ClampedArray.toString() method correctly, so the test was incorrectly failing in Safari.

IE 11's implementation of MutationObserver is buggy. It unnecessarily splits text nodes when it encounters a HTML template interpolation symbol ( "{{", for example ). So, we join the text nodes back together as a work-around.
