[svn-r578] Changes since 19980805

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

./MANIFEST
	Replaced Compression.html with Filters.html

./doc/html/Filters.html
./src/H5Ocomp.c
./src/H5P.c
./src/H5Ppublic.h
./src/H5Z.c
./src/H5Zprivate.h
	Added two extra arguments to H5Pget_filter() in order to
	retrieve the filter name.  The name is the name registered for
	the filter with H5Zregister(), but if the dataset creation
	property originally came from an existing file then the name
	is that which is stored in the file.

./tools/h5ls.c
	The `-v' option now prints the names of the filters.

./src/H5B.c
./src/H5Fistore.c
./src/H5O.c
./src/H5Oefl.c
./src/H5Oprivate.h
./src/H5P.c
	Plugged a memory leak.

./src/H5MMprivate.h
	H5MM_malloc(0) and H5MM_calloc(0) actually allocate a single
	byte in order to be sure that we get a valid pointer.

./src/H5S.c
./src/H5Sselect.c
	Fixed pointer->integer conversions in error return values in
	three places.
