jh c65c4f33f5 If dlclose() is called recursively from a _fini() function, the inner ...

dlclose() call may unload the object of the outer call prematurely
because objects are unreferenced before _fini() calls.

Fix this by unreferencing objects after calling objlist_call_fini() in
dlclose(). Therefore objlist_call_fini() now calls the fini function if
the reference count of an object is 1. In addition we must restart the
list_fini traversal after every _fini() call because another dlclose()
call might have modified the reference counts.

Add an XXX comment to objlist_call_fini() about possible race with
dlopen().
