- the various information queries MUST be executed with
  the '--no-print-directory' or risk polluting values
  in the information queries.

  This is mostly seen with the 'canCompile' test for tutorials running
  in parallel.

ENH: add wmake '-show-path-c', '-show-path-cxx' as per 1912 and later

- backported fix from develop

- 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 latest version,
  including -test-tutorial forwarding.

- adjust foamConfigurePaths to latest version

- removal of gperftools default config, as per develop

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

- log to stdout when explicitly enabled

- 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.

- 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

STYLE: add typedefs for interpolation tables

- 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

- we know they have already protected by an is_contiguous check,
  so the class-memaccess warning/error can be suppressed.

- The case files may contain #... comment lines
- The geometry file may contain an optional "extents" entry
- Properly handle element id specifications (off|assign|ignore|given).

- Partially handle node id specifications (off|assign|ignore|given).
  Treat "given" like "ignore", since results in the lightest amount of
  coding and in many cases the "given" node ids are in fact 1-based
  contiguous values and thus no different than "ignore" for our
  purposes.

ENH: downgrade error on type-mismatch to a warning

- Ensight data files generated by OpenFOAM will start with the name of
  the data type (Eg, "scalar", "vector" etc), but this convention may
  fail for data files that have been generated elsewhere.

BUG: RASModelVariables::SpalartAllmaras cannot be combined with an fvMotionSolver diffusivity which depends on wall distances (fixes #1501)

- wmake -version, --version option (alias for -show-api)
  for consistency with standard system tools

- triggers rpmlint warnings
