[svn-r8683] Purpose:

    Code optimization

Description:
    Use 'size_t' instead of 'hsize_t' to track the number of elements in
memory buffers, especially for type conversion.

Platforms tested:
    Solaris 2.7 (arabica)
    FreeBSD 4.10 (sleipnir) w/parallel
    Too minor to require h5committest
