 In [changeset:"28542"]:
 {{{
 #!CommitTicketReference repository="" revision="28542"
 Because PHP can be configured without `--filter`, it is not 100% safe to
 use `filter_var()`. This is problematic for casting `"false"` to `false`,
 as PHP always casts it to `true`. `FILTER_VALIDATE_BOOLEAN` fixes this,
 but it may not be available.

 Add a new function, `wp_validate_boolean()`, to replace `filter_var( $var,
 FILTER_VALIDATE_BOOLEAN )`.

 Fixes #28170.
