[svn-r298] Changes since 19980219

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

./html/Files.html
./src/H5C.c
./src/H5Cpublic.h
./src/H5Ffamily.c
./src/H5Fprivate.h
./src/H5Fsplit.c
./test/tstab.c
	Added file-access property functions.

	The split driver takes file extensions as properties.

./src/H5A.c
./src/H5Aprivate.h
	Added some comments. Changed H5A_destroy() to call the free
	function on all the atoms that are destroyed. This fixes a bug
	where the file boot block isn't updated if the file isn't
	closed before calling exit().

	Removed extra `*' and `&' from some places.

./src/H5AC.c
	Replaced an occurrence of NO_ADDR with NULL.

./src/H5Odtype.c
./src/H5T.c
./src/H5Tconv.c
./src/H5Tpkg.h
	Data types of compound members are pointers.

./H5private.h
	Some changes to make lseek64() work on Irix 5.3 where header
	files don't realize that `long long' works.

./acconfig.h
./configure.in
	Removed definition for PHDF5 since it looks like everyone is
	useing HAVE_PARALLEL now.

./configure.in
./src/H5detec.c
	Added checks for gethostname() and getpwuid().
