This simplifies the specification of patch faces in blockMeshDict which
now do need not have any particular ordering of the block vertices.

Change based on patch provided by Hassan Kassem

during re-reading of the fvSchemes dictionary

to simplify construction of dimensionedScalar properties and avoid the
duplication of the name string in the constructor call.

so that the specification of the name and dimensions are optional in property dictionaries.

Update tutorials so that the name of the dimensionedScalar property is
no longer duplicated but optional dimensions are still provided and are
checked on read.

This malloc overrides the one provided by GLIBC and calls mallocNan
which initializes the allocated block of memory to NaN if enabled by the
FOAM_SETNAN environment variable.

to avoid warnings from Clang

This resolves a whole range of issues and work-arounds with earlier
releases.  This version of icpc is more or less compatible with the
latest gcc and clang compilers and only required one hack to avoid
warnings from PackedBoolList.H.

This resolves issues with and complexities in the virtual function inheritance

Also removed __GNUC__ conditional compilation statements which are no
longer needed.

Added calls to setFluxRequired for p, p_rgh etc. in all solvers which
avoids the need to add fluxRequired entries in fvSchemes dictionaries.

Added calls to setFluxRequired for p in all incompressible solvers which
avoids the need to add fluxRequired entries in fvSchemes dictionary.

Will add calls to setFluxRequired to the rest of the solvers.

cellCoBlended: New surfaceInterpolation scheme based on CoBlended using the cell-based Courant number

    This scheme is equivalent to the CoBlended scheme except that the Courant
    number is evaluated for cells using the same approach as use in the
    finite-volume solvers and then interpolated to the faces rather than being
    estimated directly at the faces based on the flux.  This is a more
    consistent method for evaluating the Courant number but suffers from the
    need to interpolate which introduces a degree of freedom.  However, the
    interpolation scheme for "Co" is run-time selected and may be specified in
    "interpolationSchemes" and "localMax" might be most appropriate.

    Example of the cellCoBlended scheme specification using LUST for Courant
    numbers less than 1 and linearUpwind for Courant numbers greater than 10:
    \verbatim
    divSchemes
    {
        .
        .
        div(phi,U)  Gauss cellCoBlended 1 LUST grad(U) 10 linearUpwind grad(U);
        .
        .
    }

    interpolationSchemes
    {
        .
        .
        interpolate(Co) localMax;
        .
        .
    }
    \endverbatim

The standard merge-algorithm is N^2 over the face-points and uses a
geometric proximity test for the merge.  These are both choices for
implementation simplicity and are rather inefficient for large meshes.
I have now implemented an experimental linear topological merge
algorithm which is VERY fast and effective for meshes of any size.
Currently it will merge internal faces on meshes of arbitrary complexity
but does not yet handle edge or face collapse needed for wedges and
other degenerate blocks.

The new fast-merge algorithm may be selected using the optional
"fastMerge" entry:

fastMerge yes;

and if not present the standard N^2 algorithm will be used.

posPart returns a value or field in which the value or values are set to
0 if negative

negPart returns a value or field in which the value or values are set to
0 if positive

Needs rewriting to avoid unnecessary code duplication, preferably using
standard OpenFOAM interpolation functionality.
