In parallel the sets are reconstructed. e.g.

mpirun -np 6 checkMesh -parallel -allGeometry -allTopology -writeSets vtk

will create a postProcessing/ folder with the vtk files of the
(reconstructed) faceSets and cellSets.

Also improved analysis of disconnected regions now also checks for point
connectivity with is useful for detecting if AMI regions have duplicate
points.

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

All patches are preserved if the 'keepPatches' option is set true.

to have the prefix 'write' rather than 'output'

So outputTime() -> writeTime()

but 'outputTime()' is still supported for backward-compatibility.

Also removed the redundant secondary-writing functionality from Time
which has been superseded by the 'writeRegisteredObject' functionObject.

GeometricField: Renamed internalField() -> primitiveField() and dimensionedInternalField() -> internalField()

These new names are more consistent and logical because:

primitiveField():
primitiveFieldRef():
    Provides low-level access to the Field<Type> (primitive field)
    without dimension or mesh-consistency checking.  This should only be
    used in the low-level functions where dimensional consistency is
    ensured by careful programming and computational efficiency is
    paramount.

internalField():
internalFieldRef():
    Provides access to the DimensionedField<Type, GeoMesh> of values on
    the internal mesh-type for which the GeometricField is defined and
    supports dimension and checking and mesh-consistency checking.

Non-const access to the internal field now obtained from a specifically
named access function consistent with the new names for non-canst access
to the boundary field boundaryFieldRef() and dimensioned internal field
dimensionedInternalFieldRef().

See also commit 22f4ad32

When the GeometricBoundaryField template class was originally written it
was a separate class in the Foam namespace rather than a sub-class of
GeometricField as it is now.  Without loss of clarity and simplifying
code which access the boundary field of GeometricFields it is better
that GeometricBoundaryField be renamed Boundary for consistency with the
new naming convention for the type of the dimensioned internal field:
Internal, see commit 4a57b9be

This is a very simple text substitution change which can be applied to
any code which compiles with the OpenFOAM-dev libraries.

Given that the type of the dimensioned internal field is encapsulated in
the GeometricField class the name need not include "Field"; the type
name is "Internal" so

volScalarField::DimensionedInternalField -> volScalarField::Internal

In addition to the ".dimensionedInternalField()" access function the
simpler "()" de-reference operator is also provided to greatly simplify
FV equation source term expressions which need not evaluate boundary
conditions.  To demonstrate this kEpsilon.C has been updated to use
dimensioned internal field expressions in the k and epsilon equation
source terms.

1. Any non-blocking data exchange needs to know in advance the sizes to
   receive so it can size the buffer.  For "halo" exchanges this is not
   a problem since the sizes are known in advance but or all other data
   exchanges these sizes need to be exchanged in advance.

   This was previously done by having all processors send the sizes of data to
   send to the master and send it back such that all processors
   - had the same information
   - all could work out who was sending what to where and hence what needed to
     be received.

   This is now changed such that we only send the size to the
   destination processor (instead of to all as previously). This means
   that
   - the list of sizes to send is now of size nProcs v.s. nProcs*nProcs before
   - we cut out the route to the master and back by using a native MPI
     call

   It causes a small change to the API of exchange and PstreamBuffers -
   they now return the sizes of the local buffers only (a labelList) and
   not the sizes of the buffers on all processors (labelListList)

2. Reversing the order of the way in which the sending is done when
   scattering information from the master processor to the other
   processors. This is done in a tree like fashion. Each processor has a
   set of processors to receive from/ send to. When receiving it will
   first receive from the processors with the least amount of
   sub-processors (i.e. the ones which return first). When sending it
   needs to do the opposite: start sending to the processor with the
   most amount of sub-tree since this is the critical path.

Patch contributed by Bruno Santos:
 - "etc/config.sh/CGAL":
   - Indented the contents of the recently added if block.
   - Added comment about using system versions.
   - Library paths are now only added if the respective version is not "boost-system" and "cgal-system".

 - "src/renumber/Allwmake":
   It now relies on the previous file to get the version for
   Boost (the same way as in "makeCGAL"). This is so that it will also
   build "SloanRenumber" if "boost_version" is set to "boost-system".

 - "applications/utilities/mesh/generation/Allwmake":
   It now also relies on the script "config.sh/CGAL" to get the
   version for CGAL. If "cgal_version" is set to "cgal-system", it
   will now also build "foamy*Mesh" utilities and respective
   libraries.
