Changeset 50129 for trunk/src/wp-includes/functions.php

Message:

Users: enable admins to send users a reset password link.

Add a feature so Admins can send users a 'password reset' email. This doesn't change the password or force a password change. It only emails the user the password reset link.

The feature appears in several places:

• A "Send Reset Link" button on user profile screen.
• A "Send password reset" option in the user list bulk action dropdown.
• A "Send password reset" quick action when hovering over a username in the user list.

Props Ipstenu, DrewAPicture, eventualo, wonderboymusic, knutsp, ericlewis, afercia, JoshuaWold, johnbillion, paaljoachim, hedgefield.
Fixes #34281.
