Added LinkMsgReader::NeedsReply() method. Completely redone ServerApp messaging: no more "replyport" from BAppServerLink; instead, the registered client reply port is used. Fixed some more weak messaging stuff. ServerApp now recognizes if an unknown message needs a reply, and sends it - for example, the "Screen" preferences app no longer hangs, but crashes on start :) Made LinkMsgReader::Read() virtual again, since it's needed by RAMLinkMsgReader.cpp. Renamed BPortLink::GetNextReply() to GetNextMessage(). Some more cleanup. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@13004 a95241bf-73f2-0310-859d-f6bbb57e9c96
