- needed for the lld linker (eg, AMD aocc compiler)

ENH: report relative paths for output for easier reading

- generated too much output that also missed topology changes,
  which prevents proper post-processing

- when used for example with wallShearStress, the stress field is
  initially created as incompressible but later updated with the
  correct compressible/incompressible dimensions.

  If this field is sampled as a surface and stored on the registry
  the dimensions should be reset() and not '=' assigned, since that
  causes a dimension check which will obviously fail.

- occurs with newer gcc on ubuntu impish (gcc-11.2.0), but may perhaps
  actually be related to `-flto=auto` or to the destruction order of
  the static variables (race condition?).

  Leaving the compat table around for automatic cleanup does not
  impact on other lookups (which are nullptr checked anyhow).

TUT: hopperEmptying: add an example for KinematicReynoldsNumber
DOC: ThermoReynoldsNumber/KinematicReynoldsNumber: correct the usage examples

- 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.

COMP: respect FOAM_BUILDROOT for wmake -queue

STYLE: fix stray paraview setting

- 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))
            (1.4 (0.5 0.1 0.5))

            (1.6 (0.1 0.5 0.5))
            (1.8 (0.5 0.5 0.9))
            (2.0 (0.9 0.5 0.5))
            (2.2 (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;
                }
            }
        }
