- "$FOAM_USER_APPBIN" and "$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

functionObject: change default behavior of 'end()' to do nothing rather than calling execute and write
Time: call functionObject 'execute()' and 'end()' for last time-step

Now the operation of functionObject 'end()' call is consistent between running and post-processing

Revert "functionObject: change default behavior of 'end()' to do nothing rather than calling execute and write"

This reverts commit 4fda55b2.

LduMatrix/SolverPerformance: Changed nIterations from label to labelType corresponding to the type solved

Now the number of iterations to solve each component in a segregated
solution are stored and returned in the SolverPerformance class.
