ENH: adjust internal storage of PackedList to ensure that all unused
     internal storage elements are guaranteed to always be bit-wise
     zero. This makes the PackedBoolList implementation easier, and
     also greatly eases much of the book-keeping.
     Bits are now also zeroed on PackedList::clear()

Note: in PackedList, require packing at least 2 items otherwise it is
     more efficient to use a normal list.

Exception: applyWallFunctionBoundaryConditions.C cannot split #include
directives.

STYLE: use findIndices instead of findAll for coordinateSystems

- aspect ratio and cellDeterminant do not use 3rd direction
- wedges are properly check for having opposite one

PV3FoamReader: Use the vol-field name rather than volPointInterpolate<vol-field name> for the VTK point fields

- avoids things like "volPointInterpolate(U)", but will likely cause
  issues when used together with identically named Lagrangian fields!

- allows better inheritance of models, since the coefficients
  dictionary can be made to match the derived class.

Now instead of looking up RASModel we can lookup turbulenceModel instead.

multiphaseInterFoam: changed alphaContactAngleFvPatchScalarField to multiphaseAlphaContactAngleFvPatchScalarField

to avoid name clashed with the version of alphaContactAngleFvPatchScalarField in the interfaceProperties library.
