[svn-r328] Changes since 19980318

----------------------
./src/H5B.c
./src/H5Bprivate.h
./src/H5G.c
./src/H5Gnode.c
./src/H5Gpkg.h
./src/H5Gpublic.h
./src/H5Gstab.c
	Implemented H5Giterate().  However, since most functions can't
	take a group ID in place of a file ID yet, there's not a whole
	lot that the operator can do besides print the name or something.

./test/H5O.c
	Fixed writing of four uninitialized bytes to the file as part
	of an object header.

./test/istore.c
	For some reason, `mpirun -np 1 istore' results in extra
	arguments on the command line that istore doesn't understand.
	I'm probably forgetting to call some MPI function in
	main(). Albert, Kim?  So I commented out the `exit(1)' for the
	time being.
