Commit f9e3a2955d removing the MAXSCREEN limit left the screen
number too unlimited, and allowed any positive int for a screen number:
Xvfb :1 -screen 2147483647 1024x1024x8
Fatal server error:
Not enough memory for screen 2147483647
Found by Parfait 0.3.7:
Error: Integer overflow (CWE 190)
Integer parameter of memory allocation function realloc() may overflow due to multiplication with constant value 1112
at line 293 of hw/vfb/InitOutput.c in function 'ddxProcessArgument'.
Since the X11 connection setup only has a CARD8 for number of SCREENS,
limit to 255 screens, which is also low enough to avoid overflow on the
sizeof(*vfbScreens) * (screenNum + 1) calculation for realloc.

Instead of just closing the log when everything is done, put one more
message in stating that we're actually terminating. Users or scripts that
look at the Xorg.log will then know that a) the server has terminated
properly and b) why the server terminated (to some degree, given that most
real-world errors will be caused by AbortServer()).

A grep on xorg/* revealed there's no consumer of this define.
Quote Alan Coopersmith:
"The consumer was in past versions of the headers now located
in proto/x11proto - for instance, in X11R6.0's xc/include/Xproto.h,
all the event definitions were only available if NEED_EVENTS were
defined, and all the reply definitions required NEED_REPLIES.
Looks like Xproto.h dropped them by X11R6.3, which didn't have
the #ifdef's anymore, so these are truly ancient now."

With the MD/SD device hierarchy we need control over the generation of the
motion history as well as the conversion later before posting it to the
client. So let's not let the drivers change it.
No x.org driver currently uses it anyway, linuxwacom doesn't either so dumping
it seems safe enough.
