headers/private/shared is newer, though with small interface changes. * Removed the unnecessary Debug.h include in headers/private/shared/ObjectList.h. * Adjusted sources using these headers, mostly by adding missing includes. * Lots of automatic whitespace cleanup. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30123 a95241bf-73f2-0310-859d-f6bbb57e9c96
