to LinkReceiver, LinkMsgSender to LinkSender, and put everything into the BPrivate namespace. Made AppServerLink a cheap object - it will use the applications receiver/sender and not create its own buffers. Fixed broken communication stuff here and there (mostly Font.cpp). Put the newly introduced set|get_system_colors() into the BPrivate namespace - please don't introduce private functions into the public namespace!!! Also fixed their broken communication use, as Darkwyrm obviously forgot about it again: the sequence Flush(); GetNextMessage() without error checking is purely wrong and can make the app hang and/or crash! :-) Other minor cleanup. The input_server used some test mode with the haiku build target which is probably wrong. Hopefully I did not forget anything this time. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@13128 a95241bf-73f2-0310-859d-f6bbb57e9c96
