[svn-r518] Changes since 19980720

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

./doc/html/H5.format.html
./src/H5Oattr.c
./src/H5Odtype.c
./src/H5Oefl.c
./src/H5Olayout.c
./src/H5Osdspace.c
./src/H5Oshared.c
	Added version numbers to some object header messages so we can
	update them easier in the future.  The library currently just
	gives up if the version numbers don't match, but in the future
	the library could handle multiple versions of a message.

./test/testhdf5.c
	Removed an argument from the H5version() call that I missed
	last time.
