[svn-r6719] Purpose:
Bug Fix Description: A resource leak happened if the H5Fget_access_plist() function was called. What was happening: the driver ID and info parts of the property list copied in H5Fget_access_plist were being overwritten, but those properties were copied initially, so we lost information. Solution: Before copying over those values, call the H5F_acs_close() function to close those values. Platforms tested: Modi4 (Parallel & Fortran) Arabica (Fortran) Verbena (Fortran & C++) Misc. update:
