Sprinkle H5_ATTR_FORMAT over printf(3)-like functions in tools and fix issues (#1423)

* Correct some conversion specifications.

* Replace many "%lld" occurrences with "%" PRIuHSIZE except for a few
instances where PRIdHSIZE was appropriate.  Remove a couple of casts and
use correct format strings, instead.

* Copy values from a possibly unaligned buffer to aligned local variables
instead of casting and dereferencing pointers into the buffer.

* Committing clang-format changes
