[svn-r730] Changes since 19980928

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

./MANIFEST
	Changed freebsd2.2.1 to freebsd2.2.7 to match change in file name.

	Added a few missing files.  Are all of these supposed to be
	distributed?

./test/istore.c
	Implemented split ratios as documented in previous
	e-mails. Frank, the new API functions are H5Pget_btree_ratios()
	and H5Pset_btree_ratios().

./src/H5Sall.c
./src/H5Shyper.c
./src/H5Spoint.c
./src/H5Sprivate.h
	Added more type checking for the data transfer property list
	passed to these functions.

./src/H5D.c
	Added a dataset transfer property list as an argument to
	H5D_allocate() for the parallel version in order to pass split
	ratios down to H5F_istore_lock().  Eventually we won't need
	the split ratios for H5D_allocate() because we'll build a
	completely full B-tree from the leaves up, but it might be
	useful to have other transfer properties at that level
	anyway.  I always caled H5D_allocate() with &H5D_dflt_xfer.

./MANIFEST
./test/Makefile.in
./test/overhead.c	[NEW]
	Added an `overhead' test run by `make timings'.

+/*-------------------------------------------------------------------------
+ * Function:	H5Pset_btree_ratios
+ *
+ * Purpose:	Sets B-tree split ratios for a dataset transfer property
+ *		list. The split ratios determine what percent of children go
+ *		in the first node when a node splits.  The LEFT ratio is
+ *		used when the splitting node is the left-most node at its
+ *		level in the tree; the RIGHT ratio is when the splitting node
+ *		is the right-most node at its level; and the MIDDLE ratio for
+ *		all other cases.  A node which is the only node at its level
+ *		in the tree uses the RIGHT ratio when it splits.  All ratios
+ *		are real numbers between 0 and 1, inclusive.
+ *
+ * Return:	Success:	SUCCEED
