COMP: regularize linkage ordering and avoid some implicit linkage (#1238)

Description
    Base-class for thermophysical properties of solids, liquids and gases
    providing an interface compatible with the templated thermodynamics
    packages.

liquidProperties, solidProperties and thermophysicalFunction libraries have been
combined with the new thermophysicalProperties class into a single
thermophysicalProperties library to simplify compilation and linkage of models,
libraries and applications dependent on these classes.

The fundamental properties provided by the specie class hierarchy were
mole-based, i.e. provide the properties per mole whereas the fundamental
properties provided by the liquidProperties and solidProperties classes are
mass-based, i.e. per unit mass.  This inconsistency made it impossible to
instantiate the thermodynamics packages (rhoThermo, psiThermo) used by the FV
transport solvers on liquidProperties.  In order to combine VoF with film and/or
Lagrangian models it is essential that the physical propertied of the three
representations of the liquid are consistent which means that it is necessary to
instantiate the thermodynamics packages on liquidProperties.  This requires
either liquidProperties to be rewritten mole-based or the specie classes to be
rewritten mass-based.  Given that most of OpenFOAM solvers operate
mass-based (solve for mass-fractions and provide mass-fractions to sub-models it
is more consistent and efficient if the low-level thermodynamics is also
mass-based.

This commit includes all of the changes necessary for all of the thermodynamics
in OpenFOAM to operate mass-based and supports the instantiation of
thermodynamics packages on liquidProperties.

Note that most users, developers and contributors to OpenFOAM will not notice
any difference in the operation of the code except that the confusing

    nMoles     1;

entries in the thermophysicalProperties files are no longer needed or used and
have been removed in this commet.  The only substantial change to the internals
is that species thermodynamics are now "mixed" with mass rather than mole
fractions.  This is more convenient except for defining reaction equilibrium
thermodynamics for which the molar rather than mass composition is usually know.
The consequence of this can be seen in the adiabaticFlameT, equilibriumCO and
equilibriumFlameT utilities in which the species thermodynamics are
pre-multiplied by their molecular mass to effectively convert them to mole-basis
to simplify the definition of the reaction equilibrium thermodynamics, e.g. in
equilibriumCO

    // Reactants (mole-based)
    thermo FUEL(thermoData.subDict(fuelName)); FUEL *= FUEL.W();

    // Oxidant (mole-based)
    thermo O2(thermoData.subDict("O2")); O2 *= O2.W();
    thermo N2(thermoData.subDict("N2")); N2 *= N2.W();

    // Intermediates (mole-based)
    thermo H2(thermoData.subDict("H2")); H2 *= H2.W();

    // Products (mole-based)
    thermo CO2(thermoData.subDict("CO2")); CO2 *= CO2.W();
    thermo H2O(thermoData.subDict("H2O")); H2O *= H2O.W();
    thermo CO(thermoData.subDict("CO")); CO *= CO.W();

    // Product dissociation reactions

    thermo CO2BreakUp
    (
        CO2 == CO + 0.5*O2
    );

    thermo H2OBreakUp
    (
        H2O == H2 + 0.5*O2
    );

Needed to create generic compressible turbulence model library

The old separate incompressible and compressible libraries have been removed.

Most of the commonly used RANS and LES models have been upgraded to the
new framework but there are a few missing which will be added over the
next few days, in particular the realizable k-epsilon model.  Some of
the less common incompressible RANS models have been introduced into the
new library instantiated for incompressible flow only.  If they prove to
be generally useful they can be templated for compressible and
multiphase application.

The Spalart-Allmaras DDES and IDDES models have been thoroughly
debugged, removing serious errors concerning the use of S rather than
Omega.

The compressible instances of the models have been augmented by a simple
backward-compatible eddyDiffusivity model for thermal transport based on
alphat and alphaEff.  This will be replaced with a separate run-time
selectable thermal transport model framework in a few wee...
