 * Function:	H5P__set_filter
 *
 * Purpose:	Adds the specified FILTER and corresponding properties to the
 *		end of the data or link output filter pipeline
 *		depending on whether PLIST is a dataset creation or group
 *		creation property list.  The FLAGS argument specifies certain
 *		general properties of the filter and is documented below.
 *		The CD_VALUES is an array of CD_NELMTS integers which are
 *		auxiliary data for the filter.  The integer vlues will be
 *		stored in the dataset object header as part of the filter
 *		information.
 *
 * 		The FLAGS argument is a bit vector of the following fields:
 *
 * 		H5Z_FLAG_OPTIONAL(0x0001)
 *		If this bit is set then the filter is optional.  If the
 *		filter fails during an H5Dwrite() operation then the filter
 *		is just excluded from the pipeline for the chunk for which it
 *		failed; the filter will not participate in the pipeline
 *		during an H5Dread() of the chunk.  If this bit is clear and
 *		the filter fails then the entire I/O operation fails.
 *		If this bit is set but encoding is disabled for a filter,
 *		attempting to write will generate an error.
 *
 *              If the filter is not registered, this function tries to load 
 *              it dynamically during run time.
 *
 * Return:	Non-negative on success/Negative on failure
