- deprecate argList::additionalArgs() method and remove uses of it

- also provide size() method, which returns the number of arguments

- make centrally available via #include "addOverwriteOption.H"

default values for motion state.

For non-premixed combustion using sensible enthalpy.

STYLE: drop surface extraction from foamToStarMesh

- retain surfZone names when writing surfaces
- remove surface extraction/writing from meshWriter since it now
  duplicates what the meshedSurface class can do.

orientation != I at start.

Being more careful with when using directions relative to the absolute
axes or the direction of something relative to its initial direction.

Renaming p0, v0 to pInitial, vInitial to be clearer.

fixedOrientation constraint does not need a reference orientation, as
it is not to move at all, relative to any orientation, so the
Cartesian axes are fine.

initialOrientation.

Rename of IO to more understandable terms.  Rename ref to initial
where correct - ref is to do with the object being in Q = I state,
inital is to do with where things are when the motion starts and
pointDisplacement and value are zero.

Adding initialOrientation so that non Q = I initial states are
correct.

- sets turbulence viscosity to zero for the patch
- providees access to the yPlus() function so that the yPlusRAS utility gives
  sensible values

Uses globalMeshData::mergePoints to topologically merge mesh points.
Also now require all patches on all processors so cleaned up all code for
handling zero-sized patches.

- Added helper classes to simplify the handling of the injector properties
- Added new reacting multiphase injection model variant

Now mapDistribute structure to pull data from slaves to master and vice versa.

In case of differing pointsInstance and facesInstance it will
- read the points belonging to the facesInstance
- construct and write the mesh belonging to the facesInstance
  (so with the old, facesInstance, points)
- additionally write the current points to pointsInstance

- This avoids dependency on lex/flex and provides better encapsulation
  for buffer switching. As a result, the maximum number of open files
  only corresponds to the include depth.
