86c393fc09 - Add some more x86 instructions to emulate, 
- emulate VGA read mode 0,
- emulate VGA write mode 1,
- minor cleanup.

Protel's Easytrax, a free PCB layout program, almost runs now; there are
still some problems with the keyboard emulation, but the graphics are fine
(albeit a bit slow).

e1b4d8d074 Use STD{ERR,IN,OUT}_FILENO instead of their numeric values. The 
definitions are more readable, and it's possible that they're
more portable to pathalogical platforms.

bba1ea063e Fix breakage introduced in rev 1.26, with the introduction of 
absoluate pathnames starting with /usr/src.

This fixes the installworld target for the case where the source tree is
not in /usr/src.

040395f4dd Rewrite video emulation. Features: 
- slightly more accurate VGA hardware emulation;
- more int 10 functions, especially wrt to palette handling;
- first shot at graphics support;
- mode switching.

Bugs:

- graphics too slow;
- only 16 color modes work for now;
- works only under X, and only with 16 bit TrueColor visuals;
- far from being genuinely useful (I can play an old EGA game now, though
  (mahjongg.exe)).

Also, the code has been cleaned up a bit (more to come in a separate commit).

00d25f512c Initiate deorbit burn sequence for <machine/console.h>. 
Replace all in-tree uses with necessary subset of <sys/{fb,kb,cons}io.h>.
This is also the appropriate fix for exo-tree sources.

Put warnings in <machine/console.h> to discourage use.
November 15th 2000 the warnings will be converted to errors.
January 15th 2001 the <machine/console.h> files will be removed.

ce1fc2b2df Fix problems introduced in the previous commit: 
*	Do not use explicit paragraphing (Pp) to separate list items.
*	Do not use semi-colons to punctuate list items; the use or
	periods eases maintenance.
*	Do not mark up external shell commands as internal commands
	(Ic).
*	Do not introduce new hard sentence breaks.

d355b81dd4 Don't build with X support if DESTDIR is defined. This prevents 
breaking a cross-build caused by taking the X libraries on the
build machine. In general this means that we never compile with
X support. The user has to manually compile doscmd for that.

535b692091 Unbreak doscmd after the sigset_t change: 
doscmd heavily depends on struct sigcontext which luckily is mostly passed
between functions as usion regcontext_t. By redefining union regcontext_t in
terms of mcontext_t almost all bases are covered.

It also seems to me that doscmd was in a transitional state. The redundant
definitions made it difficult to get a clear overview and could easily cause
oversight. To make sure my changes were ok, I went as far as to complete the
transition. It was not exactly necessary, but I expect to have to come back
here some more ("whistle" if I'm wrong :-).
