Patches contributed by Mattijs Janssens:

splitMeshRegions: handle flipping of faces for surface fields

subsetMesh: subset dimensionedFields

decomposePar: use run-time selection of decomposition constraints. Used to
    keep cells on particular processors. See the decomposeParDict in

$FOAM_UTILITIES/parallel/decomposePar:
  - preserveBaffles: keep baffle faces on same processor
  - preserveFaceZones: keep faceZones owner and neighbour on same processor
  - preservePatches: keep owner and neighbour on same processor. Note: not
    suitable for cyclicAMI since these are not coupled on the patch level
  - singleProcessorFaceSets: keep complete faceSet on a single processor
  - refinementHistory: keep cells originating from a single cell on the
    same processor.

decomposePar: clean up decomposition of refinement data from snappyHexMesh

reconstructPar: reconstruct refinement data (refineHexMesh, snappyHexMesh)

reconstructParMesh: reconstruct refinement data (refineHexMesh, snappyHexMesh)

redistributePar:
  - corrected mapping surfaceFields
  - adding processor patches in order consistent with decomposePar

argList: check that slaves are running same version as master

fvMeshSubset: move to dynamicMesh library

fvMeshDistribute:
  - support for mapping dimensionedFields
  - corrected mapping of surfaceFields

parallel routines: allow parallel running on single processor

Field: support for
  - distributed mapping
  - mapping with flipping

mapDistribute: support for flipping

AMIInterpolation: avoid constructing localPoints
