- Now that the metisDecomp uses the metis definition for float/double,
  do not need to verify the scalar sizes.

Note:
- could drop precision qualifier for metis, scotch installation
  (include, lib) as being unneeded, but it is simpler to keep them
  and continue to use the FOAM_EXT_LIBBIN path
  (in case other ThirdParty software is compiled with different
  precisions).

Based on patch contributed by Alexey Matveichev
Resolves feature-request http://bugs.openfoam.org/view.php?id=2330

- Cannot pass through to underlying list constructor directly.

- As this constructor was broken, there seem to be a number of
  workarounds scattered in the code. Could revisit them in the future
  as part of code-style:

      edgeMesh(const Xfer<pointField>&, const Xfer<edgeList>&);
      CompactIOField(const IOobject&, const Xfer<Field<T>>&);
      GlobalIOField(const IOobject&, const Xfer<Field<Type>>&);
      IOField(const IOobject&, const Xfer<Field<Type>>&);

- Condition is there to catch cases where the vtkSurfaceFormat returns
  no zones (which should never be the case), but assigns a fallback
  value without first resizing.

- This format is fortunately little-used (or never used) since its
  inception.

  Using raw stream operators to write zones, points and faces in a
  single file was not well thought out - the output content varies
  with the Face template type (face, triFace, labelledFace), which
  makes it not very robust at all.

  The static read in OFSsurfaceFormat also has a bug - keeping
  transcribed faces from being passed through.

  Conclusion: removing it makes more sense that repairing and still
  not having something good.

  Do retain stream operators for MeshedSurface and UnsortedMeshedSurface,
  since they are useful for passing around data
  (eg, between processors), but they shouldn't be used for files.

- since Icc is actually mentioned in bashrc/cshrc it is consistent to
  set these values accordingly.

- Cannot test if these older reader modules actually build,
  owning largely to build issues since with paraview 3.14 (Feb 2012)
  and paraview 3.98 (Dec 2012) themselves.

- updated code to use current API level 142.

- ThirdParty build of tecio now uses CMake.

Improvements to the conversion utilities

Various changes associated with issue #204.

* Reduced code duplication for handling prostar conversion and IO
* Simple conversion to/from AVL/FIRE geometries
* New library basis for conversion to/from CCM geometries - handles multiple regions, conformal interfaces etc. No support for film or 2d shell geometries
* Improved infrastructure for writing VTK content. Will propagate usage through other parts of the code in the future.

See merge request !76

Note: classes are prefixed with 'foamVtk' instead of 'vtk' to avoid potential
conflicts with VTK itself.

foamVtkCore
~~~~~~~~~~~
- General very low-level functionality.

foamVtkPTraits
~~~~~~~~~~~~~~
- Traits type of functionality for VTK

foamVtkOutputOptions
~~~~~~~~~~~~~~~~~~~~
- The various format output options as a class that can be passed to
  formatters etc.

foamVtkCells
~~~~~~~~~~~~
- Intended for unifying vtkTopo and PV-Reader code in the future.
- Handles polyhedron decompose internally etc

foamVtkOutput, foamVtkFormatter
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Output helpers.
- Selector for individual formatters.
  Currently write all scalar data a 'float' (not 'double'). Can
  revisit this in the future.

- Reduce code duplication by moving out common functionality
  into STARCDCore.

- reuse for foamToTecplot360 and foamToVTK.
- remove dependency on vtkMesh where possible.

Feature keep sampled pids

Rebased version of merge request !58, following ticket closure for issue #104 .

See merge request !75

- For merging meshedSurf content from parallel sources.
  Ensures zoneIds are properly preserved for sampling in parallel.

Current state
~~~~~~~~~~~~~

Current producers of the region information:
 * sampledTriSurfaceMesh

Current consumers of the region information:
 * nastran writer. The zone ids passed through as PSHELL Ids (with offset 1).

Limitations

  The per-face region association is preserved, but the face/element
  sort order gets lost in reconstruction. Would need to attach
  additional information to the sampled surface and use that for
  sorting, but this would also imply that sampled values be written
  indirectly (or resorted) too to match the order. Zone ids are passed
  through, but not their names. After reconstruction, zone ids are no
  longer contiguous. Re-sorting (as mentioned above) would solve this
  too, but again at the cost of more complexity when writing.

- unhide indexing of element/property ids (pass as const parameters).
  Proper indexing is the responsiblity of the caller.

- Allows passing of additional information (per-face zone ids) or possibly
  other things, while reducing the number of arguments to pass.

- In sampledTriSurfaceMesh, preserve the region information that was
  read in, passing it onwards via the UnsortedMeshSurface content.

  The Nastran surface writer is currently the only writer making use
  of this per-face zone information.
  Passing it through as a PSHELL attribute, which should retain the
  distinction for parts. (issue #204)

- use surfFaces() to return the templated list of faces.
  This frees up the method 'faces()' to be used as a virtual method,
  which will be needed at a later stage.

- relied on 'export' keyword, which was removed in commit ac0a67da

ENH: foamConfigurePaths support for additional items:

    -label 32|64            specify label size
    -system name            specify 'system' compiler to be used
    -thirdParty name        specify 'ThirdParty' compiler to be used

    -boost ver              specify boost_version
    -boostArchPath dir      specify BOOST_ARCH_PATH
    -cgal ver               specify cgal_version
    -cgalArchPath dir       specify CGAL_ARCH_PATH
    -clang ver              specify clang_version for ThirdParty Clang
    -cmake ver              specify cmake_version
    -fftw ver               specify fffw_version
    -fftwArchPath dir       specify FFTW_ARCH_PATH
    -metis ver              specify METIS_VERSION
    -metisArchPath dir      specify METIS_ARCH_PATH

- Follow similar pattern as per boost/CGAL with the '*-none' to disable,
  and '*-system' for system installations.

  Also support central non-ThirdParty installations by specifying the
  version as "*-system", but also providing the fully qualified
  *_ARCH_PATH too.

ENH: Verify label and scalar sizes used in the metis header.

- ensure they match with expected values, which can be obtained via
  the OpenFOAM definitions for WM_LABEL_SIZE and WM_PRECISION_OPTION
