d397408818 Usage style sweep: spell "usage" with a small 'u'. 
Also change one case of blatant __progname abuse (several more remain)
This commit does not touch anything in src/{contrib,crypto,gnu}/.

6a8074206f Mark some parameters as unused. 
Make more code depend on '#ifndef NO_X' so we don't get unused warnings
when compiling without X.

fa8baa7a9e Fixed the BINGRP handling mess. 
EXEGRP and EXEMODE are used to install DOS (EXE format) binaries.
doscmd(1) can optionally be installed as ``setgid kmem''.
Hence the assignment operator for EXEGRP.

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).

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).
