Provide a way for Theme/Plugin developers to get a list of user contact methods

[johnnyb]

When templating an author page it is useful to be able to provide a list of social media links. There's great support for adding custom links using the user_contactmethods filter, but there's no public way to get a list of those contact methods without the user's other info mixed in.

There is a private function _wp_get_user_contactmethods(), that does this. Why not make it public?

[johnnyb]

I'll submit a patch in a few minutes.

Make the method public.

[johnnyb]

Patch added. It simply declares the function public, and removes the _ from the beginning of the function name, (and from calls to the function).

We could also provide a private wrapper for the public function if we need to reserve the right to modify the private implementation at some point.

[SergeyBiryukov]

I guess the cleaner approach would be to leave the private function as is and introduce a public wrapper.

[johnnyb]

Public wrapper for private method.

[johnnyb]

The new patch uses the public wrapper instead of renaming the private method.
