[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.
