X reinit code trapped

Hi, Mike!

About videoadapter reinit on SIGHUP under X

	I am partialy success, but i have not ready for use patch!
It is very simple. When DM sends SIGHUP to X, then function
Dispatch() break eternal cycle and return. Dispatch() is called
from dix/main.c main() function. X count each restart in the
variable serverGeneration. Our task is creation on additional
condition checking
	if(serverGeneration > 1 )
in the main() function. I think , beter is our paralel trying.
Seems screenInfo overwriting and InitOutput() must be disabled
when serverGeneration > 1.
May be only single dix/main.c main() function must be patched
and we got stable output over all X sessions. Output initialised
on X startup only.
Of course on Ctrl-Alt-Backspace X dies anyway.
