- added namespace to remuxers

Browse Source 
- increased WRITERBUFSIZE - buffer was too small for high bandwidth content
- removed cStreamdevStreamer::m_Running
- eliminated potential busy waits in remuxers
- updated cTSRemux static helpers to code of their VDR 1.6.0 counterparts
- re-enabled PES vor VDR 1.7.3+. Streamdev now uses a copy of VDR 1.6.0's
  cRemux for TS to PES remuxing.
- make sure that only complete TS packets are written to ringbuffers
- use signaling instead of sleeps when writing to ringbuffers
- optimized cStreamdevPatFilter PAT packet initialization
- fixed cStreamdevPatFilter not processing PATs with length > TS_SIZE - 5
- use a small ringbuffer for cStreamdevPatFilter instead of writing to
  cStreamdevStreamers SendBuffer as two threads mustn't write to the same
  ringbuffer
