[svn-r4675] Purpose:
Backward Compatibility Fix Description: One of H5P[gs]et_sieve_buf_size's parameters changed between v1.4 and the development branch. Solution: Added v1.4 compat stuff around H5P[gs]et_sieve_buf_size implementation and testing to allow v1.4.x users to continue to use their source code without modification. There are no C++ or FORTRAN wrappers for these functions. There are also no regression tests for these functions... :-( Platforms tested: FreeBSD 4.4 (hawkwind)

+/*-------------------------------------------------------------------------
+ * Function: H5Pset_sieve_buf_size
+ *
+ * Purpose: Sets the maximum size of the data seive buffer used for file
+ * drivers which are capable of using data sieving. The data sieve
+ * buffer is used when performing I/O on datasets in the file. Using a
+ * buffer which is large anough to hold several pieces of the dataset
+ * being read in for hyperslab selections boosts performance by quite a
+ * bit.
+ *
+ * The default value is set to 64KB, indicating that file I/O for raw data
+ * reads and writes will occur in at least 64KB blocks.
+ * Setting the value to 0 with this API function will turn off the
+ * data sieving, even if the VFL driver attempts to use that strategy.
+ *
+ * Return: Non-negative on success/Negative on failure
