Pavlovian response to compiler warnings...

... attempt to squash them.  For now we can get most of the way by
writing a simple write_or_goto_error() macro for write(), and the
equivalent for read().

One of the warnings, for the return value of chdir(), is silly, because
we're already in an error case, and we really can't do anything sensible
if the chdir fails.  Try to deal with it anyway.
