[svn-r516] Changes since 19980720

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

./doc/html/H5.format.html
./src/H5F.c
./src/H5Gprivate.h
./src/H5Oshared.c
	Added file alignment fields: the boot block has an extra
	reserved address field.  The symbol table entry scratch pad
	space was reduced from 24 bytes to 16 bytes.  The index
	permutation was moved earlier in the data type message for
	compound data types and extra padding was added.  Four bytes
	of padding was added to the shared message format.
