A little more abstraction in the WP_oEmbed class

[johnbillion]

The logic for determining the oEmbed provider for a given URL is contained within the get_html() method of the WP_oEmbed class.

I'd like to be able to determine whether or not a given URL has a supported oEmbed provider. There's no method in the WP_oEmbed class to do this, and I've copied the logic from get_html() into my own function.

Patch coming up shortly.

24381.patch​ simply moves the logic for determining the provider for a URL into a new method, get_provider().

Abstracting this seems logical, though I'm surprised we currently do a return false followed a filterable return.

I guess an argument can be made that the "oembed_result" filter should apply if there's actually a result though.

Also, might as well add hook docs while we're in there.

24381.2.patch​ refreshes the patch to take into account the hook docs that have since been added. Also adds the new get_provider() method above get_html() so the diff is clearer.
