I was proposing type safety, thinking there might be a better way than
replacing image_error and add_to_log by macros.  Didn't find one, did
the macro thing, didn't find any bugs, so probably not worth a commit.

I kind of think tiff_handler should use image_error, not add_to_log, but
the two have been equivalent forever.

While we can mix and match Lisp_Objects and POD C types freely in
varargs situations, it seems, all the symbols would clash (I thought %S
was safe, but doprnt.c makes it an alias for %s), and there's little
point anyway since using nonstandard format specifiers breaks
ATTRIBUTE_FORMAT_PRINTF.

So no real proposal left here.  listn is a strange animal and we should
probably use Flist instead, but that should wait until purespace is
gone, so no patch there, either.
