[svn-r322] Changes since 19980313

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

./configure.in
./configure
./test/iopipe.c
	Added check for system(3)

./config/freebsd2.2.1
./config/linux
	Added -DH5D_DEBUG to the debug flags.

./src/H5D.c
./src/H5Dprivate.h
./src/H5P.c
./src/H5Ppublic.h
./src/H5Sprivate.h
./src/H5Ssimp.c
./html/Datasets.html
	Finally implemented strip mining in the I/O pipeline, placing
	a user-defined upper bound on the amount of temporary memory
	used by the pipeline.  The default is 1MB type conversion and
	background buffers allocated/freed on demand.  However, the
	size can be changed and/or application-allocated buffers
	supplied with H5Pset_buffers() called on the data transfer
	property list passed to H5Dread() and H5Dwrite().

	Minor optimizations to H5Dread() and H5Dwrite().  More coming
	later...

./test/dsets.c
	Added calls to H5Pset_buffer() to test application-defined
	temporary buffers in the I/O pipeline.

./test/Makefile.in
	Removed `iopipe' from the list of confidence tests.  Saying
	`make timings' in the test directory runs timing tests.  I did
	this because (1) they don't really test anything new, and (2)
	they can take a long time to run.
