reactingTwoPhaseEulerFoam/twoPhaseCompressibleTurbulenceModels/kineticTheoryModels: Added support for fvOptions

fvOptions are transferred to the database on construction using
fv::options::New which returns a reference.  The same function can be
use for construction and lookup so that fvOptions are now entirely
demand-driven.

The abstract base-classes for fvOptions now reside in the finiteVolume
library simplifying compilation and linkage.  The concrete
implementations of fvOptions are still in the single monolithic
fvOptions library but in the future this will be separated into smaller
libraries based on application area which may be linked at run-time in
the same manner as functionObjects.

fixedMultiPhaseHeatFlux: Calculates a wall temperature that produces the specified overall wall heat flux
across all the phases in an Eulerian multi-phase simulation.

Intended to be used with copiedFixedValue to ensure that phase wall
temperature are consistent:
    - Set 'fixedMultiPhaseHeatFlux' boundary for one of the phases
    - Use 'copiedFixedValue' for all the other phases.

reactingEulerFoam/interfacialModels/wallDampingModels: Added interpolatedWallDamping abstract base-class
To simplify linear, sine and cosine wall-damping implementation

New lift model supporting near-wall damping using the new
wallDampingModels.

e.g.

lift
(
    (air in water)
    {
        type            wallDamped;
        lift
        {
            type            constantCoefficient;
            Cl              0.5;
        }
        wallDamping
        {
            type            linear;
            Cd              0.5;
        }
    }
);

in which a linear near-wall damping function min(y/(Cd*d), 1) is applied to the constant
coefficient lift model.  Additional wall-damping functions will be added.

to allow iteration over the energy equations to improve stability for phase-change.
Additionally if nEnergyCorrectors is set to 0 the energy equations are
not solved which may be beneficial during the startup of some cases.

Avoids the clutter and maintenance effort associated with providing the
function signature string.

to support phase volume fraction changes due to pressure

The new NotImplemented macro uses __PRETTY_FUNCTION__ for GNU compatible
compilers otherwise __func__ to provide the function name string.

Now combinations of incompressible, compressible phases with or without
mass-transfer are supported efficiently.
