fix 2 stupid h_mgr_shutdown bugs leading to failure to close some leaked handles at exit (see bug 26)

Browse Source 
- was iterating over all HDATA slots up to last_in_use, but it is
inclusive
- when closing, wasn't resetting refcount, so h_free kept those with
refcount > 1 open

This was SVN commit r1158.
