Also moved global classes which should be in the Foam namespace into it.

PolynomialEntry: Templated polynomial DataEntry to support all basic field types from scalar to tensor
This allows polynomial functions for e.g. velocity to be specified in the uniformFixedValue BC

Consider a linear function for Ux(t) with Uy and Uz = 0:

    inlet
    {
        type            uniformFixedValue;
        uniformValue    polynomial
        (
            ((10 0 0)   (0 0 0))
            ((100 0 0)  (1 0 0))
        );
    }

Improves efficiency for moving-mesh cases

advectionDiffusionPatchDistMethod: Calculation of approximate distance to nearest patch for all cells
and boundary by solving the Eikonal equation in advection form with diffusion smoothing.

wallDist/patchDistMethods/Poisson: New method for fast calculation of an approximate wall-distance field
by solving Poisson's equation

Currently these vectors are generated at the same time as the wall-distance field
by the same run-time selected algorithm.  This will be changed so that the wall-reflection
vectors are only generated and stored if required.

When using models which require the wallDist e.g. kOmegaSST it will
request the method to be used from the wallDist sub-dictionary in
fvSchemes e.g.

wallDist
{
    method meshWave;
}

specifies the mesh-wave method as hard-coded in previous OpenFOAM versions.

In preparation for run-time selectable methods

Note:
    In order to avoid unexpectedly poor results I think it would be
    better if sub-cycling in time were limited to static meshes and
    solid-body motion only and the Vsc() function removed and I will
    consider this for the next release with the addition of a check for
    solid-body motion in the case that sub-cycling is applied.  Now that
    MULES support semi-implicit operation there is less need for
    sub-cycling and I would recommend that you use this approach in
    interDyMFoam for your complex mesh motion cases.

To compile with 64bit labels set

WM_LABEL_SIZE=64

in ~/OpenFOAM/dev/prefs.sh

source ~/.bashrc

then Allwmake in OpenFOAM-dev.

This will build into for example OpenFOAM-dev/platforms/linux64ClangDPInt64Opt

If WM_LABEL_SIZE is unset or set to 32:

WM_LABEL_SIZE=32

the build would be placed into OpenFOAM-dev/platforms/linux64ClangDPInt32Opt

Thus both 32bit and 64bit label builds can coexist without problem.
