[svn-r151] Changes since 19980105

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

./config/freebsd2.2.1
./config/linux
        Added -UH5O_DEBUG to the debug flags.  Turn this on to get
        lots of lines on stderr to show what objects are opened and
        closed.

./src/H5C.o
./src/H5Cpublic.h
./test/dsets.c
./test/tfile.c
        Split H5Cget_prop() and H5Cset_prop() into functions for each
        property.

./src/H5D.c
./src/H5Dpublic.h
./src/H5Gstab.c
./src/H5O.c
./src/H5Ocont.c
./src/H5Ocstore.c
./src/H5Odtype.c
./src/H5Oefl.c
./src/H5Oistore.c
./src/H5Oname.c
./src/H5Onull.c
./src/H5Oprivate.h
./src/H5Osdspace.c
./src/H5Ostab.c
./src/H5P.c
./src/istore.c
./test/tohdr.c
        Object header functions now understand constant
        vs. non-constant messages.

./src/H5F.c
./src/H5Fprivate.h
        The file OID can be closed before other OID's.

./src/H5Flow.c
        H5F_addr_defined() is a macro in this file.

./src/H5G.c
./src/H5Gpublic.h
./test/tstab.c
        A current working group cannot be deleted.

./src/H5Gent.c
./src/H5Gpkg.h
        Removed unused functionality.

./src/H5public.h
        Includes <sys/types.h> for size_t.
