- partial revert for 13740de4 (#2158)

  MS-MPI does not currently have a MPI_Comm_create_group(),
  so keep using MPI_Comm_create() there.

  Only affects multi-world simulations.

CONFIG: retain dummy version of libPstream.dll

- retain as libPstream.dll-dummy so that it is available for
  manual replacement of the regular libPstream.dll (#2290)

  Keep extra copy of libPstream.dll as libPstream.dll-msmpi
  (for example) for manual replacement.

- this is now consistent with what the internal
  "get(Vol|Surface|Point)Field" methods deliver
  (ie, zero-gradient for volume, calculated otherwise).

  Still some slight inconsistencies with what the internal
  "new(Vol|Surface|Point)Field" methods deliver however.
  There they are always "calculated"

Enables particles to interact with mesh faces (decsribed using faceZones).

    faceInteraction1
    {
        type            faceInteraction;
        faceZones
        (
            (blockageFaces    stick)
//            (blockageFaces    escape)
//            (blockageFaces    rebound) // not applicable for this test case (!)
        );

        dMin            0;
        dMax            1;
    }

The faceZones entry is a list of (faceZoneName interactionType), where
interaction type is either stick, escape or rebound.

- Now only has the options 'point' and 'disk' (deprecated movingPoint)
  - moving state is based on the type of Function1

- The position and direction entries are Function1-types, e.g. for the 'table'
  type the entries could be:

        position        table
        (
            (  0 (0.1 0.5 0.5))
            (0.2 (0.5 0.9 0.5))
            (0.4 (0.9 0.5 0.5))
            (0.6 (0.5 0.1 0.5))

            (0.8 (0.5 0.5 0.9))
            (1.0 (0.5 0.9 0.5))
            (1.2 (0.5 0.5 0.1))

The parcel initial velocity can now be set using the new `velocityType`
entry, taking one of the following options:

- fixedValue   : (default) same as earlier versions, requires U0
- patchValue   : velocity set to seed patch face value
- zeroGradient : velocity set to seed patch face adjacent cell value

Example usage:

        model1
        {
            type            patchInjection;
            massTotal       1;
            SOI             0;
            parcelBasisType mass;
            patch           cylinder;
            duration        10;
            parcelsPerSecond 100;
            velocityType    patchValue;
            //velocityType    zeroGradient;
            //U0              (-10 0 0);
            flowRateProfile constant 1;
            sizeDistribution
            {
                type        normal;
                normalDistribution
                {
                    expectation 1e-3;
                    variance 1e-4;
                    minValue 1e-5;
                    maxValue 2e-3;
                }
            }
        }

ENH: Copying alphatLiquid value to alphatVapour for boiling regimes.

When using correlations for boiling regimes the phases next to the
wall are not relevant to these. Therefore the alphat is copied
accordingly from the alphat for liquid.
Only in the sub-cooling RPI model the partition of heat flux
between vapour and liquid is considered.

- provides a simple means of defining/modifying fields. For example,

  ```
  <name1>
  {
      type    exprField;
      libs    (fieldFunctionObjects);
      field   pTotal;

      expression  "p + 0.5*(rho*magSqr(U))";
      dimensions  [ Pa ];
  }
  ```
  It is is also possible to modify an existing field.
  For example, to modify the previous one.
  ```
  <name2>
  {
      type    exprField;
      libs    (fieldFunctionObjects);
      field   pTotal;
      action  modify;

      // Static pressure only in these regions
      fieldMask
      #{
          (mag(pos()) < 0.05) && (pos().y() > 0)
       || cellZone(inlet)
      #};
      expression  "p";
  }
  ```

  To use as a simple post-process calculator, simply avoid storing the
  result and only generate on write:
  ```
  <name2>
  {
      store            false;
      executionControl none;
      writeControl     writeTime;
      ...
  }
  ```

- literal lookups only for expression strings

- code reduction for setExprFields.

- changed keyword "condition" to "fieldMask" (option -field-mask).
  This is a better description of its purpose and avoids possible
  naming ambiguities with functionObject triggers (for example)
  if we apply similar syntax elsewhere.

BUG: erroneous check in volumeExpr::parseDriver::isResultType()
