[svn-r6656] Purpose:
Bug fix & new feature. Description: The global heap 'dirty' flag was missed in the last round of changes to the metadata cache and was not using the new "cache_info.dirty" flag. Solution: Switched to using correct flag for marking dirty objects in the metadata cache. Also, added new metadata callback for marking a piece of metadata as clean without writing it back to the file. Platforms tested: FreeBSD 4.8 (sleipnir) w/C++ Linux 2.4 (burrwhite) w/FORTRAN Solaris 2.7 (arabica) w/FORTRAN IRIX64 6.5 (modi4) w/parallel & FORTRAN (h5committest not run due to my ongoing difficulties with C++ on burrwhite).
