[svn-r439] Changed the PHDF test programs substantially. Used to be just one
big testphdf5.c file. Broke it into modules of related routines. testphdf5.c -- main routine and global variables initialization plus some ulitility routines. t_file.c -- tests of file operations using parallel I/O. t_dset.c -- tests of datasets operations.
