[svn-r1240] Changes since 19990427

----------------------

./tools/h5ls.c
	Added a `--address' (`-a') switch which causes h5ls to display
	file addresses for raw data. For contiguous datasets it's just
	a nice simple number, but for chunked datasets it's a list of
	logical dataset coordinates, file addresses, filter masks, and
	storage sizes.

	Changed `--dump' switch to `--data'.

./src/H5D.c
./src/H5F.c
./src/H5Fprivate.h
	Enhanced the indexed-storage B-tree iterator so it can dump
	raw data addresses (and other info) to the standard error
	stream.

	Added H5Ddebug() so h5ls has a way to dump addresses for
	datasets. I'm not sure what else this API function should do,
	so I think we should discuss it before we document it. So far,
	h5ls is the only thing that uses it, and we can easily change
	that.

./src/H5Tconv.c
./test/dtypes.c
	Finally had a chance to verify Paul's H5T_conv_s_s (general
	string to string conversions) bug fixes and incorporate them
	into H5T_conv_f_f (general floating-point to floating-point
	conversions) and H5T_conv_i_i (general integer to integer
	conversons). Thanks Paul.

./src/H5D.c
./src/H5S.c
./src/H5Sprivate.h
	Added performance timers around data space read and write
	callbacks. They were already there for the gather/scatter
	callbacks.

	The timings for read/write callbacks are displayed along with
	gather/scatter when data space debugging is turned on.

./bin/iostats
	Updated to print totals. Added a `--fast' option that doesn't
	do any output except the totals and is much faster.

./bin/trace
	Changed __unused__ to UNUSED to match source code.

./config/gnu-flags
	Updated error message for pgcc. I've sent bug reports to the
	pgcc people but the new version still has the same bug.

./configure.in
./config/conclude.in
./config/depend.in
	Fixed dependencies for non-GNU makes when run in a directory
	other than the hdf5 source tree.

	Updated GNU `make dep' rules to copy the distributed
	dependencies for non-GNU makes into the source tree when run
	in some other directory.
