fbcmap.c and XFree86Server

[Brian Paul]

This is a proposal to split the xserver/fb/fbcmap.c file into two.

As it is now, there's a test for XFree86Server that controls how the 
functions are compiled.  If XFree86Server is defined the functions are 
compiled as wrappers for mi functions.  Otherwise, the functions are 
compiled in a totally different way independent of mi.

This means that if fbcmap.c is compiled the wrong way, it probably won't 
do what you want.  This has caused me grief with DMX on two occasions.

I think we're getting away from using the XFree86Server symbol, right? 
If so, this is another step in that direction.

I'd like to move the later half of fbcmap.c, starting at line 589 into a 
new fbcmap_mi.c file.  See fbcmap.c at 
http://gitweb.freedesktop.org/?p=xorg/xserver.git;a=blob;h=9cf5bcbf5b1b5e8971dbcdae20a6cd041e53d75c;hb=e44f106ffc796c025abdfb66717c06db8b12b4e4;f=fb/fbcmap.c

Then, in the Makefile.am files that used -DXFree86Server and fbcmap.c 
I'll get rid of the -DXFree86Server switch and use fbcmap_mi.c instead.

If there's no objections, I'll check in the changes in a day or so.
