The jstk code for Joysticks is not used by any module, was never actually compiled and uses an API
that is deprecated these days.
No reason to keep it.
Add a generic 'ring the bell' function (console bell on Linux and BSD,
/dev/audio on Solaris), and add DDX functions for this. Make this the
core keyboard's bell.
Port Xvfb and Xnest to this.
Port XFree86 to this, with OS-specific hooks for Linux, BSD, and Solaris
taken from foo_io.c in the old layer.
Get rid of almost all uses of these definitions. They're still defined for
delinquent out-of-tree drivers, and also for the Mesa build. As well as
for miinitext.c. But largely gone.
