haiku/headers/private/app/LinkMsgSender.h
Axel Dörfler dd10337fd0 Renamed BAppServerLink to AppServerLink, BPortLink to PortLink, LinkMsgReader
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.
