Remove the rest of the 20+ year-old memory debugging gunk. Discussed
with deraadt@

Remove a gazillion useless casts to void*
Eliminate a couple function pointer casts, fixing the function to match
in one case

Replace xrealloc() with xreallocarray(). Break-out the 'log and die'
function as xmallocfailure() and use that in the locations where
reallocarray's checks alone aren't sufficient.
