1. HPCC-32960 Fix epoll memory corruption issues …

   Although the SelectItem 'items' array is protected by a CS,
   epoll_wait can receive pending events for SelectItems that have
   been deleted, which were then link counted and caused corruption.
   
   Like the select handler version, avoid deleting the SelectItem's
   when items are removed, instead mark them deleted and let the
   triggerselect() approach remove them on the main thread.
   
   Also fix a theoretical issue when adding a existing socket to
   CSocketEpollThread, it did not check other CSocketEpollThread's
   to see if it needed to be removed. (given default hdlPerThrd is
   UINT_MAX, it will not have happened).
