Tom Tromey cafb34387d Remove unnecessary casts of NULL 
I noticed some unnecessary casts of NULL.  This removes all the
unnecessary ones, leaving only ones where we must ensure that NULL has
pointer type for passing through varargs.

I removed a couple of useless casts of 0 that I noticed while writing
this.

Tested by rebuilding.
