misc: again fixing many printf format strings

misc: again fixing many printf format strings

This is again a huge patch regarding printf format strings to
fix compiler warnings seen on clang/OSX.

I'm trying to follow these rules strictly:

 #type      #format   #cast
 uintmax_t   %ju      -
 intmax_t    %jd      -
 uint64_t    PRIu64   -
 int64_t     PRId64   -
 size_t      %zu      -
 ssize_t     %zd      -
 ino_t       %ju      (uintmax_t)
 off_t       %jd      (intmax_t)
