Add and use pcdisplay_cursor_init(). Still a couple of nits with this, I

will resolve when I can test properly.

- mc6845's cursor is disabled by punching bit 6 of cursor start register.

- Add new option (PCDISPLAY_SOFTCURSOR) that provides a large, non-blinking
cursor in software.

-implement new wscons font handling with separate download and selection

calls
-support use of 2 fonts simultanously; this costs the ability to
"highlight", ie to use the upper 8 colours
-define screen types "80x25bf" and "80x50bf" which use this ability
-add conditional code to deal with the weird mapping of pcvt's
supplemental fonts

Allow to deallocate also the currently visible virtual screen (unless
...
it is the console).
This requires vva_show_screen() to catch the case where it has no screen
to switch from, ie no need to save the current state.

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.
