Bug 1652 -  h5lget_info_by_idx_f missing/broken functionalit
  * added returned val_sel, link_type and address that were missing

In the process, fixed the integer type in H5lget_info_f for address and val_sel

  * wrote test for val_sel, address, and link_type returned values

  * to check address values added h5Oopen_by_addr_f function and test program.

Tested: smirom (pgf90/pgcc, ifort/icc)
