Add compiler-specific "examine printf format" attributes to printfs.

Functions that take a printf-style format get a new annotation, which
produces a bunch of compiler warnings when you use printf impoperly.
This change adds the annotations and fixes the warnings.

We now must use PRId64 for 64-bit numbers and the PRIsz for size_t.
