- add support by using updated foamEtcFile from 1806, which also add
  the '-config' short-cut option.

- also fix incorrect documentation in forces functionObject and
  interRegionExplicitPorositySource fvOption.

- use floor/truncate instead of round. Backport of changes in the
  develop-pre-release branch.

- tie the MPI rules to the base compiler type *without* its version.
  Eg, linux64Gcc (which exists) instead of linux64Gcc81

- was using st_atim instead of st_mtim for the nanoseconds

- value of followLink was being ignored (it was always being followed).

This thermo is used with multiComponentMixture in rhoThermo type

- occurred when the initial mesh distribution was missing cells on
  some processors.

- using const reference to temporary was failing.  Remedy by using a
  direct copy, which is a reasonable solution since surfZone content
  is quite minimal.

- downgrades some diagnostics about nonconformant code from errors to
  warnings. Oddly enough, the errors actually arise from STL library
  elements shipped with gcc itself. Affects kahip compilation with
  gcc-6, gcc-7

The minimum number of particles per parcel can now be set in the
injection model input, e.g.:

    model1
    {
        type            ...;
        massTotal       ...;
        parcelBasisType ...;
        minParticlesPerParcel 1; <-- new optional entry
        SOI             ...;
        ...

Uses a value of 1 by default if the entry is not present.  The value of
1 is generally recommended and beneficial for coupled cases where small
time steps can lead to the injection of too many parcels and subsequently
greatly over-predict the particle source contributions (momentum, heat,
mass transfer etc)

The non-dimensional table takes non-dimensional U as entry, not flow rate

- runTimeModifiable change to the dictionary not being propagated to
  the underlying functionObjects

- problems when the cloud was not available on all processors.

- NB: ensight measured data only allows a single cloud, but
  foamToEnsight writes all clouds.
