Support extra $args in `load_template()`

[dcavins]

Thanks to some changes in WP 5.5 (​https://make.wordpress.org/core/2020/07/17/passing-arguments-to-template-files-in-wordpress-5-5/), it's now possible to pass extra arguments to a template file. We use load_template() (​https://developer.wordpress.org/reference/functions/load_template/) in bp_locate_template(), and the attached patch supports the passing of an extra $args parameter through our template functions to load_template().

That’s a really great idea 💡 👌!

Thanks for thinking about it 😍

Hi @dcavins patch looks good, I just suggested to also add the $args argument to bp_buffer_template_part and I've added a unit test about it.

Fantastic! Great addition and the unit test is clever!

One comment: Can we mark this test as only applying to WP >=5.5? I'm afraid that Travis's test matrix would fail it because it won't work in WP 5.4 and below.

You're right! Sorry I haven't paid attention to your concern about unit test the first time I've read your comment. I agree with you. 8350.03.patch should make sure it won't happen.

Feel free to commit it ;)

In 12726:

Pass extra args to template loading files.

Starting in WordPress 5.5, the template loading
functions will now allow additional arguments to be
passed through to the matched template file using a
new $args parameter.

This changeset passes an extra argument through
the BuddyPress template loading wrapper functions
to the underlying WordPress functions.

Props imath.

Fixes #8350.
