Add `register_post_type_args` filter for changing `register_post_type()` arguments before further processing.
Does not apply to built-in post types. Props MikeSchinkel, nickciske, engelen, swissspidy. Fixes #17447. git-svn-id: https://develop.svn.wordpress.org/trunk@34242 602fd350-edb4-49c9-b593-d223f7449a82
