    Bug Description: winsync stops working after server restart

    Fix Description: The problem really is that the server does not shutdown.
    You have to kill -9 the server.  When it restarts, the sync agreement is no
    longer working.  The problem was only observed on 32-bit platforms.  The
    size of the mmr Repl_Connection structure is different than the size of
    the winsync Repl_Connection structure.  The code was calling conn_delete()
    on the winsync Repl_Connection*.  We have to use windows_conn_delete instead.
    The repl protocol code did not have a place to do that, so I added a new
    delete_conn function pointer so that prot_free can call the right
    conn_delete function.
    Platforms tested: RHEL5 i386, RHEL6 x86_64
