[svn-r10869] Purpose: A feature

Description: For v1.7 library, family file driver has been changed.
The family member size is saved in the superblock and compared to
the size passed in through H5Pset_fapl_family().

Solution: Added test to check if we can open family file created
with v1.7 library.

Platforms tested: h5committest and fuss.

Misc. update: MANIFEST
