* plugbasedclient.c (main): Check if plugin dir could be opened.  Set
                            FD_CLOEXEC on the directory, if possible,
                            and also on both ends of the pipe.  Do not
                            allocate buffer for process in advance.
                            Free the plugin list.  Bug fix: exit if no
                            plugins found, not if any found.  Set
                            "exitstatus" in many places.  Simplify and
                            un-indent the loop reading process pipes.
                            Renamed process list iterator to "proc".
                            Bug fix:  retry password write on EINTR.
                            Free the process list properly, including
                            the process structs themselves.
