- unnecessary. Can deduce labelRange from the pair of labels.
  These are all the same:

      list[labelRange(18,3)] = 100;
      list[labelRange{18,3}] = 100;
      list[{18,3}] = 100;

  Removing the run-time handling of std::initializer_list in favour of
  compile-time deduction allows the future use of sliceRange as well.
  Eg,

     list[sliceRange{18,3,2}] = 100;
     list[{18,3,2}] = 100;

- use an IndirectListBase class for various indirect list types.

- new SortList type

  In some places the SortList can be used as a lightweight alternative
  to SortableList to have the convenience of bundling data and sort
  indices together, but while operating on existing data lists.
  In other situations, it can be useful as an alternative to
  sortedOrder.  For example,

        pointField points = ...;

        labelList order;
        sortedOrder(points, order);

        forAll(order, i)
        {
            points[order[i]] = ...;
        }

   Can be replaced with the following (with the same memory overhead)

        pointField points = ...;

        SortList<point> sortedPoints(points);

        for (point& pt : sortedPoints)
        {
            pt = ...;
        }

- new SliceList type (#1220), which can be used for stride-based
  addressing into existing lists

- Enhancements provided by Y. Inoue at RIST (http://www.hpci-office.jp)
- Use allToAll to only swap local data (excludes master processor; saves memory)
- Memory saving is noticeable >= 4000 cores

This fixed the MeshObject on Time but produced problems for the
non-regIOobject MeshObjects.

- convenient when using data structures from other codes

- fix typo in makefiles/info that affected wmake -show-compile-c

- additional safeguard in src/OpenFOAM/Make/options against self-linking.
  This is not normally required unless PROJECT_LIBS has been added into
  the link stage.

- extracts values from the arch "LSB;label=32;scalar=64" header entry
  to provision for managing dissimilar primitive sizes.

  Compensate for the additional IOobject members by narrowing the types
  for the (objectState, readOption, writeOption) enumerations

- now suppress any '#line' if the input number number is invalid
  (ie, an empty set of tokens)

- can be helpful for handling rotations within global planes

- replace (darwin) with (__APPLE__)
- replace (solarisGcc) with (__sun__ && __GNUC__)
- instead of 'darwin' -> '__APPLE'

- cease with passing a -D$(WM_ARCH) define since this adds no useful
  additional information and isn't used anywhere.

COMP: Extend size disambiguation on long (#1238)

- allows better separation from compiler settings

- use -fPIC instead of legacy -KPIC for intel compiler

solaris:
  - rename WM_ARCH from SunOS to solaris64 for consistency with wmake/rules
  - drop non-64 solaris from wmake/rules
  - remove automatic selection of FJMPI. This should be done in the bashrc
    or prefs.sh file instead.
  - remove old (likely inaccurate) exported flags, rely on wmake -show-xyz
    or user config instead

darwin:
  - remove '-Ddarwin' from the exported WM_CFLAGS, WM_CXXFLAGS.
    Not used elsewhere (ThirdParty)

STYLE: report MPI flavour (WM_MPLIB) when making mpi-related libraries

- the only code location using BiIndirectList are debug sections
  within polyTopoChange.

  No need to construct/assign directly from a BiIndirectList since
  the '()' method provides a simple alternative.

Fix provided by Gavin Ridley.

- aids with portability and maintenance (#1238)
