Does not fix the tolerance issue.

- now maintains a correct list of geometry instances, without assuming
  contiguous file numbering. However, if the numbering is contiguous,
  the more compact case representation will be used.

- an advanced feature, for example when sampling on a static patch
  while some motion occurs elsewhere. [use with caution]

- If the sampled surface dictionary is modified during run-time, the
  ensight file indexing for the geometry will become out of sync.
  This is addressed in a subsequent commit.

- this can be useful for preloading of libraries, or for utilities
  that don't use system/controlDict.

  The additional libraries can be specified individually:

      myUtil -lib lib1 -lib lib2 -lib lib3

  When specified like this, the options add up.

  Or as a 'captured' list using OpenFOAM's standard arg list handling:

      myUtil -lib '(' lib1  lib2 lib3 ')'
      myUtil -lib \( lib1  lib2 lib3 \)

  or as single argument list:

      myUtil -lib '("lib1" "lib2" "lib3")'

  When specified as a single argument, would normally take advantage
  of the transparent handling of word vs fileName and omit the string
  quotes:

      myUtil -lib '(lib1 lib2 lib3)'

ENH: dlOpen error messages now propagated into dlLibraryTable

- this makes the context more relevant and also avoids the previous
  annoyance of double warnings (one from the POSIX loader, and one
  from dlLibraryTable)

STYLE: mark -noFunctionObjects and -withFunctionObjects as 'advanced'

- reduces clutter. Still visible with -help-full

- include ragel and lemon

- rename pre-generated files to ".cc" so that they are more
  recognizable as being different from regular file content.

- should have been part of commit 9d36d3c0
  which allows us to upcast a word to a fileName.

- allows direct reading of a single entry with token checking

- add additional rule (ending '.ll') for the combination of
  flex for C-code but compiling the result as C++.
  This can be needed for re-entrant parsers.

- update bison rule to handle renaming of skeleton files.
  Use a wrap-bison script to manage this.

- alternatively can use uniformNormalFixedValue with PatchFunction1
  specification and temporal ramping.

TUT: add ramped example for simpleCar

- This improves consistency for warnAboutAge and build information
  when the API level changes

- compacter messages in some cases

STYLE: simplify output handling of line numbers

- relax casting rules
  * down-cast of labelToken to boolToken
  * up-cast of wordToken to stringToken.
    Can use isStringType() test for word or string types

- simplify constructors, move construct etc.

- expose reset() method as public, which resets to UNDEFINED and
  clears allocated storage etc.

DEFEATURE: remove assign from word or string pointer.

- This was deprecated 2017-11 and now removed.
  For this type of content transfer, move assignment should be used
  instead of stealing pointers.

- makes its use somewhat clearer and allows more future options

- new patches were added to the end of existing patches, which placed
  them _after_ the processor patches. This is incorrect.

CONFIG: remove adios1 config files

- OPENFOAM_PLUS was last used in OpenFOAM-v1712 and provided as a
  transition from OpenFOAM-v1806 until OpenFOAM-v1906

- OPENFOAM_COM was never used

- creates a std::string with space-delimited tokens, which can be sent
  to another application or even re-parsed into tokens

1) Add softWall rigidBody restrain
2) Add linearSpringDamper sixDoF restrain to work as soft rope
3) dynamicMotionSolverListFvMesh changed to dictionary based input
4) Add Time reference access to sixDof restraints
5) Add drivenLinearMotion to solidBodyMotionFunctions.
