hdf5/test/links.c
James Laird 801ca2f9cb [svn-r12452] Purpose: 
Feature

Description:
Revised Link APIs.

Solution:
New link APIs use H5L*
H5*create_expand do not create links to the objects created; this must
be done manually with H5Llink.
Added APIs to link an object given its ID (H5Llink), to copy links (H5Lcopy),
and changed creation APIs (H5Lcreate_hard and H5Lcreate_soft) and query
API (H5Lget_linkinfo instead of H5Gget_objinfo).
All old APIs are still supported in H5Gdeprec.c .

Platforms tested:
sol, mir, copper

Misc. update:
Forgot to update MANIFEST and release docs.  Will do after checkin.
