[svn-r15959] Description:
Added missing wrappers for H5Rdereference. Also, for these wrappers, improved exception handlings to report specific overloaded functions, where failure occurs. Will do the same for more functions later... Platforms tested: Linux 2.6 (kagiso) SunOS 5.10 (linew) FreeBSD (duty)
