- autoPtr to Function requires clone() method, not optional copy/move
  argument.

- fix bad character range for 'sed'

- can be useful when confronted with partial outputs

- provision for redirecting error/warning

ENH: add some scalar constants for .org compatibility (#1881)

Although it can very much be a moving target, it can prove partly
useful to have some compatibility constants/methods.

- The wholesale change of 'GREAT' -> 'great' etc (JAN-2018), makes
  user coding for multiple versions problematic. When
  COMPAT_OPENFOAM_ORG is defined, now define constants (aliases) named
  as per the openfoam.org version. Values, however, remain identical.

- For type-safe dictionary value retrieval, we have the templated
  get<> methods added around NOV-2018 and deprecated the lookupType
  method.

  The .org version followed suit in NOV-2019, but opted for renaming
  the templated lookupType method as a templated 'lookup' method.

  Using this is discouraged, but allowed when COMPAT_OPENFOAM_ORG is
  defined.

- flips state while preserving the textual representation.
  Eg, OFF <-> ON, YES <-> NO etc.

- fix test case to avoid triggering abort(), which we cannot try/catch

- not usually of any interest.
  Unifies code for Ostream and std::ostream operators

- provides a more direct means of generating a compound token without
  an Istream

- add transferCompoundToken() without Istream reference

- mark more token methods as noexcept

- was marked as transitional/deprecated (2018-02), now deleted.

- avoids unexpected stealing of the pointer.
  Use the move assignment it that is the intention.

STYLE: update cell methods

- avoid shadow variable names, range-for, etc
- simplify coding

STYLE: relocate cellModeller (compatibility) from namespace to a struct

- avoids misleading namespace clutter in doxygen

STYLE: avoid shadow variable names, add more doxygen markup

STYLE: cull some unused code from triangleFuncs

- add point() as unchecked getter method.

- add hitPoint(.., label) convenience method for common combination of
  setHit() + setIndex(label) + setPoint(..)

GIT: remove unused headers, typedefs (point2DHit.H pointHitSort.H)

- mostly reflects minor additions to Pstream methods and blockMesh
  improvements.

- slightly neater code when disabling/restoring parallel state

  New
      const bool oldParRun = Pstream::parRun(false);
      ...
      Pstream::parRun(oldParRun);

  Old
      const bool oldParRun = Pstream::parRun();
      Pstream::parRun() = false;
      ...
      Pstream::parRun() = oldParRun;

- on ArchLinux, everything is installed under /usr/include/scotch.

  The detection script uses SCOTCH_ARCH_PATH as an initial guess for
  ptscotch as well. However, on the second pass, it has an absolute
  value ("/usr") instead of a logical one ("scotch-system").
  This resulted in the logic for handling scotch+ptscotch subdirs
  being bypassed.

- the problem arises when output fields are missing on some
  processors.

  When the information is combined, the resulting HashTables can have
  different insertion orders. This poses an issue when there are hash
  key collisions and thus different chaining.

- Use sorted order.

- additional -tool= option to guide the discovery process

- support construct face from subset of labels.

- additional cellModel face() method to return a single face.

- reduce some allocations in cellModel centre/mag methods

STYLE: mark old cellModeller methods as compile-time deprecated

- deprecated in 2017, but not marked as such

STYLE: indentation, spacing in some headers

- incorrectly used const access for the tmp instead of ref()

- consistent with other blockEdge types
- adjust some debug output

Feature block mesh edges

See merge request !383

- in most cases this eliminates manually calculation of circumferential
  points.

TUT: improve parameterization of sphere blockMeshDict

- allow separate parameterization of radius, ratio of inner to outer,
  and the number of divisions in x/y/z and radial directions

- The arc will frequently enclose an angle less than 180 degrees.
  For the case, it is possible to define the arc by its endpoints
  and its centre (origin) point. For example,

      arc 0 1 origin (0 0 0);

  When defined in the way, any discrepancy in the arc radius for the
  endpoints is resolved by adjusting the origin to ensure that the
  average radius is satisfied.

  It is also possible to specify a \em flatness factor as a multiplier
  of the radius. For example,

      arc 0 1 origin 1.1 (0 0 0);

ENH: minor code cleanup for block edges

ENH: expose point appending as polyList::concat

STYLE: adjust blockMesh advanced/non-advanced options

- make -merge-points "non-advanced" (for better exposure)
- make -write-obj "advanced" (-write-vtk is preferred)

- contents to be filled with a later assignment.

  This can help avoid deduction issues when populating from a list of
  tokens, and the templated version is selected:

  ```
  template<class T>
  primitiveEntry(const keyType&, const T&);
  ```

ENH: support construct empty ITstream with given name

- populate contents later by assigment

- Eg, cannot compare addresses of DynamicList<T,16> and DynamicList<T,8>
  [clang], so compare their cdata pointers instead.

- use clear/swap paradigm for more code reuse

Note: fixed similar issue with copy/reuse constructor

- provides consistency with identity(label, label) and looks more
  familiar than using labelRange::labels()

- relocates labelRange IO operators to IntRange

ENH: make sliceRange interators random access

STYLE: scalarRanges::match() instead of predicate operator

Triggered when running e.g. postProcess

Pstream ranges

See merge request !382

- returns a range of `int` values that can be iterated across.
  For example,

      for (const int proci : Pstream::subProcs()) { ... }

  instead of

      for
      (
          int proci = Pstream::firstSlave();
          proci <= Pstream::lastSlave();
          ++proci
      )
      {
          ...
      }

- returns a range of `int` values that can be iterated across.
  For example,

      for (const int proci : Pstream::allProcs()) { ... }

  instead of

      for (label proci = 0; proci < Pstream::nProcs(); ++proci) { ... }

- wedge geometry, so topology merge results in zero-sized faces.

- only use implicit legacy handling if the "fanCurve" entry is missing
  and the "file" entry is present.
