They are both gone, and pr_pointer_t is now pr_ptr_t (pointer may be a
little clearer than ptr, but ptr is consistent with things like intptr,
and keeps the type name short).
As it is now a completely separate sub-system, there is a bit of trouble
with mouse handling in that curses must be initialized before input for
the mouse to work properly, but the basic scheme seems to be working
nicely. I suspect the solution to the init order issue is to make have
the curses sub-system initialize the terminal input driver, at least for
mouse input (ie, maybe just enable/disable mouse handing).
The queues in the curses resources struct have been cleaned up and the
threading support code (including for the queues (pipes, really)) has
been moved to its own file.
The input test app currently just prints the devices and the events as
they come in, but demonstrates the new input system working in a
separate thread (though it is currently in with the curses thread).
