[svn-r19176] Bug fix for #1239 - The filter's public function CAN_APPLY should return htri_t not
herr_t. To minimize the change of the library's behavior, in the function H5Z_prelude_callback of H5Z.c, if the return value of can_apply is FALSE and the filter is MANDATE, this function returns a FAILURE. If the return value is FALSE but the filter is OPTIONAL, this function returns a SUCCEED. During the IO, the filter will fail and return a size of zero. But the pipeline will skip this filter. Tested the same change for 1.8 on jam, linew, and amani. Tested on jam with szip.
