New callout mechanism with two major improvements over the old
...
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.
The old timeout()/untimeout() API has been removed from the kernel.

-support use of 2 fonts simultanously; this costs the ability to

Overload the generic "copyrows" function by a private one which implents
...
a "fast scroll" by setting the display start in memory.
(Only implemented for "scroll up" because this is more used. "scroll down"
is easy to add.)
This moves the semantics of "copyrows" to something like "moverows";
the contents of the new visible lines at the bottom is undefined.
The emulations can live without the original "copy" semantics.

Simple screen attribute handling for wscons.
...
The graphics device driver passes a "default attribute" for normal text
output to the wscons framework. If the emulation module needs more
attributes (for different "renditions") it can allocate them via a
callback.
For now, only the "sun" emulation makes use of it.
