- respect trailing '-', '.', '_' for the image prefix name.
  For example,

    -image press_   to accept press_*.png

- additional -mask width option (for avconv)

- SIGFPE handling, cmake configuration

CONFIG: adjust for simplified Catalyst channel naming

- no sub-channels, select volField output based in the
  (internal | boundary) dictionary switches instead

- do not need the stringOps version if there is no dictionary context

- rename Allrun.parallel to Allrun-parallel (issue #899)

- The additional output generated by #calc directives in the
  controlDict or decomposeParDict causes issues for the RunFunctions
  extraction of 'application' and 'numberOfSubdomains'.

  Avoid by using -disableFunctionEntries, which also has the side-effect
  of disabling '#include'.

- major() and minor() are GNU macros in sys/sysmacros.h
  and generates warning on some systems (eg, Ubuntu 18.04)

  use getMajor() and getMinor() as method names instead.

- corrected the mass based correction and updated the misleading function
  arguments

- moved the option to the optimisation switches, e.g.:

    OptimisationSwitches
    {
        experimentalDdtCorr 1;
    }

- default remains off/no (0)

- Don't remove the constant/polyMesh directory if it contains a
  blockMeshDict or blockMeshDict.m4 file. Offer a reminder that
  system/ is the normal place for it.

- add additional control via a Foam::infoDetailLevel flag, which is
  supported by a 'DetailLevel' macro.  Eg,

      DetailLevel << "some information" << nl

- When infoDetailLevel is zero, the stdout for all Foam::system() calls
  are also redirected to stderr to prevent child output from
  appearing on the parent.

- close stdin before exec in system call.

- convenient way to temporarily suspend the SIGFPE handler.
  Eg,

      // Normal code with SIGFPE enabled ...
      sigFpe::set();

      {
          // Ignore SIGFPE in this scope ...
          sigFpe::ignore noFpeHandling;
          ...
      }

- use Enum instead of NamedEnum
- shorter form for dimensionedScalar

- reduce verbosity about missed seeding for DTRM cloud.
  Re-enable old warnings in debug mode.

- some paraview versions (eg, on windows) don't support float, only double.

  This mostly affected the vtkSurfaceWriter.

  The foamToVTK is also affected, but since it also supports the XML
  output formats (vtp, vtu) these can be used instead.

- affected manually generated legacy output (vtkSetWriter, vtkSurfaceWriter)

- the order emitted by vtkSetWriter remains, but needs to revisited again.
