[svn-r25] ./src/H5AC.c

	We sort the cache before a complete flush because it might be
	more efficient to write things back to disk in order of
	increasing address.  If you want the old way then undef the
	SORT_BY_ADDR constant at the top of H5AC.c  I haven't
	determined which systems and I/O libraries this helps or
	hurts. (This is currently off because of a bug I need to track
	down that causes qsort() to run for a really long time).

./src/H5B.c
	Fixed a couple more bugs.

./src/H5Eprivate.h
./src/H5Eproto.h
	Added major H5E_DIRECTORY and minor H5E_EXISTS, H5E_COMPLEN.

./src/H5G.c
	Added directory-aware functions.

	The heap and B-tree are created when a directory is created
	instead of when the first symbol is added.  This simplifies
	symbol table entry caching for the directory since the cached
	value never changes now.

./src/H5Gnode.c
./src/H5Gprivate.h
	Fine tuned the B-tree K values for symbol tables assuming an
	average number of symbols is about 100 per directory.  The
	tuning minimizes storage space.

	Fixed a return value in H5G_node_cmp().

./src/H5H.c
./src/H5Hprivate.h
	Moved some macros the the header file.

./src/H5O.c
./src/H5Ocont.c
./src/H5Onull.c
./src/H5Ostab.c
	Changed the arguments for the decode method for messages.  The
	second argument is the raw message size.

	Added a class variable for native message size.

	Added H5O_reset() to free memory used internally by a message.

./src/H5Oname.c			NEW
./src/H5Oprivate.h
./src/Makefile
	The object name message.

./src/hdf5port.h
	Added defn for HDstrdup()
