Version 1.1.25vdr-1.1.25

- Fixed high CPU load during replay (thanks to Marcel Wiesweg for pointing out this
  one).
- Fixed margin handling in cRingBufferLinear.
- Now polling the output device in 'Transfer Mode' and retrying to put packets
  into the ring buffer.
- Resetting the CAM slot in case communication breaks down.
- Improved keyboard detection (thanks to Werner Fink).
- Updated 'channels.conf.terr' (thanks to Andy Carter).
- Fixed broken support for raw OSDs of plugins (thanks to Marcel Wiesweg for
  reporting this one).
- Broken CAM connections are now restored automatically.
