Message:

Introduce 'duplicate_comment_id' filter.

wp_allow_comment() disallows a comment if it matches a comment on the same
post with the same content, author email, and parent. This new filter allows
developers to circumvent or modify this logic, making the duplicate check
more or less lenient, as they see fit.

Fixes #9775.
