This allows freedom in the naming of patches when patchGroup-based
boundary specification is not used.

This reverts commit f38f0d3e.

If this clash is allowed boundary conditions set by wildcards are
processed incorrectly.

  - There will be triangles rendered inside the mesh (when
    surface-rendering), because one of the cell's triangles is defined
    as a quadrangle in VTK_WEDGE.

  - Therefore, this VTK_WEDGE representation is only used when
    decomposing the mesh, otherwise the correct representation is done
    by VTK_POLYHEDRON.

  - Furthermore, using VTK_PYRAMID gave worse result, because it renders
    2 triangles inside the mesh for the collapsed quadrangle, likely due
    to mismatch with the adjacent cell's face.

  - Using VTK_HEXAHEDRON was not tested in this iteration, given that it
    should give even worse results, when compared to using VTK_PYRAMID.

  - "$FOAM_USER_APPBIN" and "$FOAM_USER_LIBBIN" have been added to
    "foamOldDirs" in "etc/bashrc" and "etc/config.sh/unset"

  - "$OPAL_PREFIX" is now undefined in the option "SYSTEMOPENMPI" within
    "etc/config.sh/mpi", but only if the path defined in this variable
    is cleaned when using "foamCleanPath".

  - "$OPAL_PREFIX" is now also conditionally undefined in
    "etc/config.sh/unset" when the path is picked up by "foamCleanPath".

Description
    Allows specification of different writing frequency of objects registered
    to the database.

    It has similar functionality as the main time database through the
    \c writeControl setting:
      - timeStep
      - writeTime
      - adjustableRunTime
      - runTime
      - clockTime
      - cpuTime

    It also has the ability to write the selected objects that were defined
    with the respective write mode for the requested \c writeOption, namely:
      - \c autoWrite - objects set to write at output time
      - \c noWrite   - objects set to not write by default
      - \c anyWrite  - any option of the previous two

    Example of function object specification:
    \verbatim
    writeObjects1
    {
        type        writeObjects;
        libs        ("libutilityFunctionObjects.so");
        ...
        objects     (obj1 obj2);
        writeOption anyWrite;
    }
    \endverbatim
