Bug fix

Description:
    H5Gget_objname_by_idx should allow NULL for the 'name' parameter, to allow
    for querying for the name's length.

Solution:
    Allow NULL for the 'name' parameter, the internal functions were already
    ready to handle that case.

    Clean up RM information about H5Gget_objname_by_idx and
    H5Gget_objtype_by_idx also.

Platforms tested:
    FreeBSD 4.8 (sleipnir)
