[svn-r20487] Bug 1386 - allow dimension size to be zero even though it isn't unlimited. This is a follow-up checkin for
r20440 and r20469:
1. The dataspace code has another bug - when the maximal dimension isn't passed in for H5Sset_extent_simple, it
is supposed to be same as the dimension. The current library sets NULL to it. I corrected it and added a
test case to it.
2. I corrected the tests of Fortran and C++ for this problem.
Tested on heiwa, jam, and amani.
