Assume C99 fixed sized ints exist, use them (#470)

* Committing clang-format changes

* Assume C99 fixed sized ints exist, use them

* Assume H5_SIZEOF_LONG_DOUBLE != 0, `long double` has existed since C89

Note, this is only assuming that `long double` exists, no assumptions about its size have been touched.  Didn't remove any code that does things like test if `long double` and `double` have different sizes.
