oEmbed - Add a function to remove an oEmbed provider

[r-a-y]

In /wp-includes/media.php, there's the ability to add an oEmbed provider with wp_oembed_add_provider(), but no way to remove one.

The attached patch is an attempt to allow you to remove an oEmbed provider.

For the $match parameter, I've opted to allow you to match any portion of the $format key.

For example, to remove the YouTube oEmbed provider, you can use:

wp_oembed_remove_provider( '#http://(www\.)?youtube.com/watch.*#i', 'http://www.youtube.com/oembed' );

or:

wp_oembed_remove_provider( 'youtube.com', 'http://www.youtube.com/oembed' );

---

If partial matching for the $format key is undesired, let me know and I'll repatch for an exact match only.

Clever, but I think we should just have:

function wp_oembed_remove_provider( $format ) {
	require_once( ABSPATH . WPINC . '/class-oembed.php' );
	$oembed = _wp_oembed_get_object();
	if ( isset( $oembed->providers[ $format ] ) ) {
		unset( $oembed->providers[ $format ] );
		return true;
	}
	return false;
}

That was how I originally wrote the function.

I was concerned about having duplicate $format's when I just realized that $format is a key! D'oh!

So this works for me.
