Add missing format attributes

Add __attribute__ decorations for printf format checking to the places that
were missing them.  Fix the resulting warnings.  Add
-Wmissing-format-attribute to the standard set of warnings for GCC, so these
don't happen again.

The warning fixes here are relatively harmless.  The one serious problem
discovered by this was already committed earlier in
cf15fb5cabfbc71e07be23cfbc813daee6c5014f.
