[svn-r6415] Purpose:
Code cleanup Description: Changed hard-coded magic number (32) for the maximum number of filters in a filter pipeline to use a symbolic constant (H5Z_MAX_NFILTERS) instead. This limit could (and probably should) be removed to allow an unlimited number of filters in a pipeline. Platforms tested: FreeBSD 4.7 (sleipnir)
