[svn-r4670] Purpose:

    Backward Compatibility Fix
Description:
    One of H5P[gs]et_sym_k's parameters changed between v1.4 and the development
    branch.
Solution:
    Added v1.4 compat stuff around H5P[gs]et_sym_k implementation and testing
    to allow v1.4.x users to continue to use their source code without
    modification.

    These changes are for everything except the FORTRAN wrappers - I spoke with
    Elena and she will make the FORTRAN wrapper changes.
Platforms tested:
    FreeBSD 4.4 (hawkwind)

+/*-------------------------------------------------------------------------
+ * Function:	H5Pset_sym_k
+ *
+ * Purpose:	IK is one half the rank of a tree that stores a symbol
+ *		table for a group.  Internal nodes of the symbol table are on
+ *		average 75% full.  That is, the average rank of the tree is
+ *		1.5 times the value of IK.
+ *
+ *		LK is one half of the number of symbols that can be stored in
+ *		a symbol table node.  A symbol table node is the leaf of a
+ *		symbol table tree which is used to store a group.  When
+ *		symbols are inserted randomly into a group, the group's
+ *		symbol table nodes are 75% full on average.  That is, they
+ *		contain 1.5 times the number of symbols specified by LK.
+ *
+ *		Either (or even both) of IK and LK can be zero in which case
+ *		that value is left unchanged.
+ *
+ * Return:	Non-negative on success/Negative on failure
+ *
+ * Programmer:	Robb Matzke
+ *		Tuesday, January  6, 1998
+ *
+ * Modifications:
+ *
+ *		Raymond Lu, Oct 14, 2001
+ *         	Changed to the new generic property list.
