[svn-r515] Changes since 19980715

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

./doc/html/H5.format.html
./src/H5Gent.c
./src/H5Gprivate.h
./src/H5Oattr.c
./src/H5Oprivate.h
./src/H5Oshared.c
./src/H5HG.c
./src/H5HGprivate.h
	Added padding fields in symbol table entries, attribute
	messages, shared messages, and global heap objects to insure
	that things are aligned on 8-byte boundaries in the file, and
	thus in memory.  Otherwise some little endian machines
	complain (DEC Alpha) during encoding/decoding of file meta
	data.  I chose to add alignment to the file rather than
	rewriting the ENCODE/DECODE macros for the little endian case.

	Completely rewrote the section on attribute messages.

	More alignment stuff will follow.

./src/H5detect.c
	Fixed a typo `nd'->`dn'

./test/dtypes.c
	Commented out conversion tests to/from `long double' on
	machines where it's the same size as `double' to get rid of
	compiler warnings.

./doc/html/Big.html
	Fixed a couple typos.
