[svn-r1573] Changes since 19990817
----------------------

./src/H5D.c
./src/H5F.c
./src/H5Fistore.c
./src/H5Smpio.c
	Incorporated previous changes into MPIO special cases. These
	are mostly due to the fact that most of the members of the
	file->shared->fapl struct have been moved into the
	file->shared->file->shared struct (`file' is an H5F_t*).

./src/H5I.c
	Fixed a bug with closing the library w.r.t. the VFL stuff. The
	VFL layer introduced reference counts on object ID's and the
	library termination functions freed these objects in the wrong
	order. Now H5I_clear_group() does not normally remove objects
	with a reference count larger than one because it assumes that
	those objects are currently in use by the library.
