[svn-r473] Changes since 19980708
----------------------

./src/H5Fistore.c
./src/H5S.c
	Fixed places where `herr_t' functions returned NULL for
	failure: H5F_istore_get_addr() and printf(?!?) (probably
	because a printf() was in the first column :-/ so I don't know
	what function it really was that I fixed), and H5S_extent_copy().

./src/H5Fprivate.h
	Added declarations for H5F_istore_get_addr() and
	H5F_istore_allocate().

./src/H5S.c
./src/H5Sprivate.h
	Split H5Sset_extent_simple() into H5S_set_extent_simple() and
	replaced calls to the API function with calls to the internal
	function.

	Changed calls to H5Screate() to H5S_create() and H5Sclose() to
	H5S_close().

./src/H5Shyper.c
./src/H5Spoint.c
	Removed unused labels and variable.

./src/H5T.c
./src/H5Tconv.c
	Changed calls to H5Tfind() to H5T_find().

./src/H5TB.c
	Split function return type onto a separate line for five
	functions and added API tracing calls.
