- fixes various memory leaks found by valgrind and a follup closer
    code inspection of the bsddb module.  (merges r1.32 of _bsddb.c
    and an associated test case)
  - also merges the one line r1.37 _bsddb.c fix that fixes a leak on
    the rare DBEnv creation failed error path.

the end of a second function whos code was identical enough for patch
not to reject the patch.  this reverses that misapplication (only the
DBC_set_range method needed modification, not DBC_set as well).  This
problem only exists in the release32-maint branch.

pass over the unreachable weakrefs-with-callbacks to unreachable objects.

In cyclic gc, clear all weakrefs to unreachable objects before allowing any
Python code (weakref callbacks or __del__ methods) to run.

This is a critical bugfix, affecting all versions of Python since weakrefs
were introduced.
