to simplify writing common functionObjects and avoid unnecessary code duplication

Patch contributed by Bruno Santos
Resolves text report http://bugs.openfoam.org/view.php?id=2089

  - Avoids the need for the 'OutputFilterFunctionObject' wrapper
  - Time-control for execution and writing is now provided by the
    'timeControlFunctionObject' which instantiates the processing
    'functionObject' and controls its operation.
  - Alternative time-control functionObjects can now be written and
    selected at run-time without the need to compile wrapped version of
    EVERY existing functionObject which would have been required in the
    old structure.
  - The separation of 'execute' and 'write' functions is now formalized in the
    'functionObject' base-class and all derived classes implement the
    two functions.
  - Unnecessary implementations of functions with appropriate defaults
    in the 'functionObject' base-class have been removed reducing
    clutter and simplifying implementation of new functionObjects.
  - The 'coded' 'functionObject' has also been updated, simplified and tested.
  - Further simplification is now possible by creating some general
    intermediate classes derived from 'functionObject'.

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.

functionObjects: Changed options 'outputControl' -> 'writeControl' and 'outputInterval' -> 'writeInterval'

for consistency with the time controls in controlDict and to avoid
unnecessary confusion.  All code and tutorials have been updated.

The old names 'outputControl' and 'outputInterval' are but supported for
backward compatibility but deprecated.

Superseded by the more general #include dictionary directive.

etc/config.sh/scotch: Added $WM_PRECISION_OPTION for consistency

Simplified the directory structure in ThirdParty-dev/platforms

Construction failure and recovery is not handled with exceptions in functionObjectList

Exit on FatalIOError

Simplified and generalized the handling of functionObjects which fail to
construct by removing them from the list rather than maintaining an
"enabled" switch in each functionObject.

Description
    This functionObject writes objects registered to the database in VTK format
    using the foamToVTK library.

    Currently only the writing of the cell-values of volFields is supported but
    support for other field types, patch fields, Lagrangian data etc. will be
    added.

    Example of function object specification:
    \verbatim
        writeVTK1
        {
            type        writeVTK;
            functionObjectLibs ("libIOFunctionObjects.so");
            ...
            objectNames (obj1 obj2);
        }
    \endverbatim

    \heading Function object usage
    \table
        Property     | Description             | Required    | Default value
        type         | type name: writeVTK     | yes         |
        objectNames  | objects to write        | yes         |
    \endtable

applications/solvers/heatTransfer/chtMultiRegionFoam: Check there are fluid meshes present for the '-postProcess' option

Use the solver '-postProcess' command-line option instead of execFlowFunctionObjects

execFlowFunctionObjects: Replaced with script providing instructions to use the '-postProcess' option
