- useful for post-processing and data conversion tests

- Query the etc/config.sh values for ThirdParty software.
  Usable without an active OpenFOAM environment.

Issues:
- neighbouring processors use different ray since always from
owner cc to nbr cc
- growing cellZones did not correctly unmark intersections
- stand-alone baffles now always removed (if inside 'grow' region,
i.e. within 1 cell of cellZone)

- the foamConfigurePaths script is quite simplistic and aggressive in
  what it changes. This was particularly evident when using it to
  change gcc/clang versions.

  Restructured the corresponding compiler settings to define default
  versions (eg, "default_gcc_version") that limits the scope of
  changes performed by foamConfigurePaths and makes it easier to
  understand if changing manually.

BUG: bad buffer size in globalMeshData::sharedPoints()

- introduced by vector::zero -> Zero replacement (commit 683cfb9d)

- provides an indirect access to a sub-section of a list that is
  somewhat less efficient than a Foam::SubList, but supports the
  following:
    * adjustment of its addressing range after construction
    * recovery of the original, underlying list at any time

  This can be more convenient for some coding cases.
  For example,

      template<class Addr>
      void renumberFaces(IndirectListBase<face, Addr>& faces, ...);

  which can be called for

      * Specific faces:
        UIndirectList<face>(mesh.faces(), facesToChange)

      * A sub-range of faces:
        IndirectSubList<face>(mesh.faces(), pp.range())

      * All faces:
        IndirectSubList<face>(mesh.faces())

CONFIG: added IndirectListsFwd.H with some common forwarding

- the gcc c++/9 includes now inline strncpy, which obliterates
  the previous method of suppressing the warning.
  Now simply allocate additional space for the nul character.

COMP: silence some icc warnings

- the vtkCellArray internal structure was still largely oriented on
  the VTK legacy format, but has now been revised.
  https://gitlab.kitware.com/vtk/vtk/merge_requests/5682

  The `VTK_CELL_ARRAY_V2` define from vtkCellArray.h indicates
  that the newer version is being used.

* In VTK-8.2.0 and older, sizes are interwoven (prefixed) in the
  connectivity.

  Connectivity: [n1, verts..., n2, verts... ]

  When using these in vtkUnstructuredGrid, also needed a secondary
  list of offsets for each of the starting locations.

* The update version now resembles a CompactListList. For example

  Connectivity: [verts..., verts... ]
  Offsets:      [0, n1, n1+n2, n1+n2+n3... ]

  The offsets are properly handled within vtkCellArray, and dropped as
  an additional input for vtkUnstructuredGrid.

- indexing error in the output of values resulted in uniform output in
  most cases.

- allocation error for on-the-fly triangulation

ENH: changed decomposed storage from DynamicList to plain faceList for
clearer allocation control and better overhead

- rationalized some layout and comments

ENH: stream adjustments

See merge request !332

- make stream constructors explicit

- remove "using std::ifstream", "using std::iofstream" statements
  for a cleaner namespace.

* copy/move assignments for ITstream

* IStringStream: default construct and construct from std::string
  instead of Foam::string

- reduce some overhead in masterOFstream

- simplify Pstream handling of string variants (#1525)
