client_filter-data-handling.patch by Petri Hintukainen

- regonize PUSI flag in TS packets (bullet-proof section start+end indicator)
- Use own TS buffer to read directly from socket, no need for ring buffer anymore
- Re-activate all active filters after re-connection to server
- Simplify thread start/stop/running detection to current VDR style
- Update "filter closed by VDR" detection (datagram sockets
  return different errno's than pipes)
- Deliver data to first matching and active filter (do not drop data if first
  matching filter has been closed, there is quite likely new filter for it)
- Add disconnect detection to avoid 100% CPU usage in cTSBuffer::Action()
