Task #5883: Replace MPI_Init/Rank/Size/Finalise with wrapper class, reducing the code base and making sure that MPI_Finalize is *really* called at the end, and not before MPI_Free_mem in particular

- Moved OMPThread.h to CoInterface
- Added tOMPThread
- Added CoInterface/TimeFuncs.h for struct timespec functions
- Added OMPThreadSet class to register/kill groups of OpenMP threads
- Use OMPThreadSet to be able to kill slow write() calls in both Pipelines

  Also add script to set the 'current' symlink. The changes are mostly in error checking.
  The 3 added .sh scripts are not yet tested in its entirety, only parts.
  They have been derived from working scripts, but need to be retested. This is best on the cbt009 after hostname redirection (incl cbt001-008 unavail).
  Also, they may need extra functionality once tested:
    restrict to cbt001-008 or cbt009 
    do not upload/download to/from NEXUS
  Move install location of a few scripts from bin/ to sbin/.

  Most changes are renaming. 'Station' idents are unclear wrt expect values "CS001" vs "CS001HBA0".
    Parset.cc has a clear "translation" point. Added 2 TODOs, as renaming these two functions is too invasive for this task.
  Add option to restrict cobalt nodes to those that receive streams from ant fields in the obs.
    Default off, because as JD mentioned, this may exclude nodes that are needed for computing only.

Task #5555: Compute delays in caller's thread, simplifying the code. Caller is a light-weight thread already (GPUProc/Station/StationInput::StationMetaData)

Task #5555: Found and fixed 'invalid packet' in MPIData::write by properly filtering packets if obs is 16 bit, 200 MHz

Task #5555: Speed improvements: use uint64_t counters in StationInput inner loops, use payloadError bit instead of separate valid[] array, use dedicated rspDataPool per RSP board

Task #5555: Gave generateRSP a log_prop file to prevent logging from clobbering the output. For the tests, the -o parameter is used instead to circumvent the same issue.

Task #5555: Allow construction of a StationID straight from a full antenna-field name (i.e. CS001HBA0)

Task #5555: Transmit the SubbandMetaData in bulk, using one transfer/station/receiver instead of one transfer/station/subband
