- the local third-party headers are to be searched before any MPI
  include directories. This stops the situation where an mpi-specific
  version of ptscotch.h is installed into the MPI directories.

  This "system" version may well have a different SCOTCH_Num size
  (32 bit vs 64 bit) from the third-party library etc.

- can occur if MPI has be initialized for communication but OpenFOAM
  itself is operating in serial mode and thus did not attach any
  MPI buffers.

- regression was introduced by 628b2445

- change previous default (convert all faceZones unless -noFaceZones
  specified) with the default behaviour to only convert face zones on
  request.

- uses the '-faceZones' option as per foamToEnsight

- this allows it to work like readListIfPresent() but with a list as
  the return value, which can be useful for a const context.

- allows inclusion of the cyclicACMIPolyPatch mask in the same file

- the result of lsof, which is used in the etc/cshrc to locate the
  installation, may contain trailing information about host and mount
  point.

  There is also a moderate concern with people sourcing the
  file indirectly with their own version in the same directory.
  For example, a 'etc/cshrc-site' that actually sources 'etc/cshrc'.
  This leads to multiple matches in the lsof output, so we only take
  the first one, stop there and hope they didn't do something even
  trickier.

- now needs local 'set' instead of 'setenv'

- fixed inconsistency in edit of ParaView_VERSION for csh version

- report api, patch as well as the number of entries in the
  FOAM_APPBIN, FOAM_LIBBIN for a quick visual sanity check

ENH: Added new AMIWeights function object

See merge request OpenFOAM-plus!225

- the counterpart to floatVector, doubleTensor, which can be useful
  for connecting to programs that always expect double precision for
  the arguments, when using single-precision for OpenFOAM itself.

  Eg,
     doubleVector pos = ...;
     vtkcamera->SetPosition(pos.v_);

- applyToSet() automatically handles NEW like ADD, so no need to do
  so explicitly

- have 'use' as the action appears more intuitive as the first entry
  instead of 'add'. Was previously also added to vtkCloud.

- now defaults to the project-version when absolutely nothing else is
  known

STYLE: simplify internal calling in wmakeBuildInfo

- local csh variable in foreach was masking the setenv

- prefer this to using the OPENFOAM define since this improves the
  internal consistency with the build information.

  The API information could change between builds without the
  etcFiles.C being recompiled whereas the value of
  Foam::foamVersion::api is force updated during the build (triggers
  recompilation of globals.Cver)

Reports the min|max|average AMI weights to text file and optionally
writes VTK surfaces of the sum of the weights, and mask field for
ACMI patches.

Example usage:

    AMIWeights
    {
        type            AMIWeights;
        libs            ("libfieldFunctionObjects.so");
        writeControl    writeTime;
        writeFields     yes;
    }

and final residuals, nIterations. See #1115.
