[svn-r4181] Purpose:
Bug Fix, Code Cleanup, Code Optimization, etc.
Description:
Fold in the hyperslab speedups, clean up compile warnings and change a
few things from using 'unsigned' or 'hsize_t' to use 'size_t' instead.
Platforms tested:
FreeBSD 4.3 (hawkwind), Solaris 2.7 (arabica), Irix64 6.5 (modi4)
