Following the recent confusion over whether Fsignal and wrong_type_argument
return or not, I went ahead and cleaned up this whole mess.
There is now a new function `xsignal' which is similar to `Fsignal',
but is guaranteed never to return.
To further clean up the code, I've added functions xsignal0, xsignal1,
xsignal2, and xsignal3, which are like xsignal, but they take a fixed
number of arguments and build a list from those arguments which is
then passed on to xsignal.
Finally, I took the signal_error function from xfaces.c and generalized
it a bit to be useful everywhere we signal a Qerror with a string +
additional args. The arg need not be a list; if not, it is automatically
made into a 1-element list before being passed to xsignal.
There are still calls to Fsignal left in the code. Those all signal Qquit
-- which may return if the debugger says so.
