[svn-r914] Changes since 19981113
----------------------

./config/conclude.in
./test/Makefile.in
./tools/Makefile.in
	The Makefile $TESTS variable has finally been split into
	$TEST_PROGS and $TEST_SCRIPTS with the latter being the names
	of shell scripts that need to be run with `/bin/sh'.  Now we
	don't have to copy each shell script before we run it. NOTE:
	THIS CHANGE DOES NOT AFFECT THE PABLO MAKEFILE SINCE THAT FILE
	IS A COPY OF A PREVIOUSLY GENERATED MAKEFILE.

./src/Makefile.in
	Added H5Snone.c to the source list.

./src/H5G.c
	Plugged a memory leak by emptying the object type "isa" table
	when the library is closed.

./src/H5Tconv.c
./src/H5Tpkg.h
	Added 48 new type functions to take advantage of hardware for
	integer type conversions.  These functions are not registered
	in the conversion table yet because I haven't fully tested
	them.

./src/H5Tpkg.h
	Removed __unused__ qualifiers from prototypes.
