- construct from dimensioned/value, defaulting name from value.
  Can be convenient for these type of operations:

      max(.., dimensionedScalar(somedims, 0.5))

- construct from dimensioned/one, forwarding to pTraits::one.
  Can be convenient for constructors:

    volScalarField( ..., dimensionedScalar(somedims, one{}))

ENH: minor updates to zero/one classes.

- add global 'One' constant for symmetry with 'Zero'.

- use dictionary::get<..> instead of lookup in a few more places

- clearer than passing a reference to a dummy variable,
  or relying on move occuring within the copy constructor
  (historical, but should be deprecated)

STYLE: consistent autoPtr syntax for uncollated file operations

- can help in circumstances when an zero-sized entry is written on
  some processors, but the compound-type may be useful for determining
  a particular code path when re-reading the files. Ensures that the
  information is consistent on all processors.

STYLE: adjust separation of includes between List.H and UList.H

Also adds pointTopoDistance, edgeTopoDistance.

- various changes

- bin/tools/create-mpi-config to query/write values for system openmpi.
  In some cases this can be used to avoid an mpicc requirement at runtime.

- adjust openfoam session to include -test-tutorial forwarding to the
  tutorials/AutoTest. This helps with writing installation tests.

- adjust foamConfigurePaths to latest version

- removal of gperftools default config, as per develop

Feature VOF mass models

See merge request !351

Sergio Ferraris authored 5 years ago and Andrew Heather committed 5 years ago

1) Add interfaceHeatResistance model to icoReactingMultiphaseInterFoam
   This model uses a spread source for the continuity Eq.
   It is recommended for cases with good mesh resolution.

2) Adding iso-surface type of calculation for the interface for
   the kineticGasEvaporation model

3) Add switch for option to take into account volume change

4) Add poolEvaporation tutorial

- remove MSWindows components (code and makefiles)

- use cxx, hxx extensions to reduce possible confusion with other
  "list" and "vector" classes

- use C++ versions for C headers

- inadvertently set to zero instead of one (in commit 1d85fecf)

- Query the etc/config.sh/compiler for Gcc/Clang versions

- align wmake have_* scripts to support version query as per current
  develop branch

- use config.sh/ fallbacks when the corresponding *_ARCH_PATH is empty
  (eg, BOOST, CGAL, FFTW).
  This aids when building outside of the regular OpenFOAM environment.

- add '[-+.~]' to the recognized qualifiers.
  This allows simple readable names such as

      WM_COMPILER=Clang-vendor

  but also opens the FUTURE (not yet supported) possibility of
  combining in additional information. For example,

      WM_COMPILER=Clang~openmp
      WM_COMPILER=Clang+cuda~openmp

  by using '+' (add) and '~' (subtract) notation similar to what
  spack uses.

CONFIG: support 'override' rules

- if present, compiler-family 'override' rules are included after
  compiler-family 'general' rules have been included. This allows a
  central means for including dynamically generated content to
  override some values.

  Some examples:

  To handle different gcc versions (system compiler):

  wmake/rules/...Gcc/override

  ```
  ifneq (,$(findstring 9, $(WM_COMPILER)))
      cc  := gcc-9
      CC  := g++-9 -std=c++11
  endif
  ```

  To handle different openmp on Darwin (#1656):

  wmake/rules/darwin64Clang/override

  ```
  # Use lib...

- requires -Xpreprocessor
- uses 'libomp' (no 'libgomp' link)

TUT: clean up multiphase tutorials

See merge request !347

1) The sign of radiative flux (qr) for modes Power and HeatFlux was
corrected.

2) Relaxation factor implementation was incomplete. Now caching
valueFraction and refValue from  the previous time step.

- use Clang instead of Gcc for Darwin since this is its system
  compiler. The user can force use of Gcc by using Gcc92 etc.

- make etc/cshrc sed check more robust.

- replace tcsh (${%var}) syntax with ("${var}" != "")

[Fixes and ideas from Alexey Matveichev]

CONFIG: do not source the gperftools environment by default

- this is now an used feature, but can be re-enabled by advanced users
  if required.

- add edit of llvm/mesa/vtk paths. Reduce some verbosity

- include Darwin in foamInstallationTest, foamSystemCheck to avoid
  a false negative.

- as a side-effect of recent changes, command-line stripping of .gz
  extensions on input was lost. For example,

      OK:    surfaceTransformPoints file.stl ...
      Fail:  surfaceTransformPoints file.stl.gz ...

- restore the previous behaviour of silently stripping the '.gz'
  extension on input.

ENH: add triSurface::New selector entry point

- for symmetry with MeshedSurface
