	Output-only arguments have their addresses printed during
	tracing and added symbolic output for the H5F_driver_t
	arguments.  That's another reason that we should be careful to
	add `/*out*/' after arguments that are output-only and
	`/*in,out*/' after arguments that are used for both input and
	output values.

	No internal function calls H5Pget_class() anymore.

./src/H5T.c
./src/H5Tconv.c
./src/H5Tpkg.h
./src/H5Tpublic.h
	Added H5Tget_overflow() and H5Tset_overflow() so the
	application can query or set a function that will be called
	whenever an overflow occurs.  Implemented as documented in
	previous e-mail except the overflow handler gets two buffers:
	one that contains the source value and one to receive the
	optional destination value.

./test/dtypes.c
	Tests overflow handler.

./src/H5.c
	We have to declare fdopen() because I'm getting errors when
	compiling on Irix64 even though we include <stdio.h> as
	documented in the fdopen() man page.
