Log Message:
PR/58886: Jose Louis Duran: Fix freed memory access leading to SEGV,
given the following spec file (mt -f <specfile>):
------
/set type=dir
  .
    dup
    ..
    dup
      child_entry type=file
------
This happens because when calling:
          addchild(last, centry);
if it is the same entry, centry will be freed and then
          last = centry;
will point to freed memory. Make addchild return the entry that is supposed
to be used instead.
