- use InfoSwitch to disable, or via static method.

- respect the state of the argList banner when deciding to emit
  initialization information. Can otherwise end up with unwanted
  output rubbish on things like foamDictionary and foamListTimes.

- patch from Bernhard Gschaider

- use similar semantics as used for dealing with metis, scotch

- consistent with use of FOAM_SOLVERS, and reduces reliance on the FOAM_APP
  env variable

- useful for builds that don't use the ThirdParty directory at all

- just check WM_PROJECT_DIR instead.

- provide a fallback value when FOAM_EXT_LIBBIN might actually be needed.

Only strictly need FOAM_EXT_LIBBIN for scotch/metis decomposition, and
when these are actually supplied by ThirdParty.
All other ThirdParty dependencies are referenced by BOOST_ARCH_PATH etc.

Can therefore drop the FOAM_EXT_LIBBIN dependency for VTK-related
things, which do not use scotch/metis anyhow.

- has different locations on different systems
  (eg, /usr/bin/lsof or /sbin/lsof)

- this implies that jobControl is a user-resource for OpenFOAM.
  It was previously located under $WM_PROJECT_INST_DIR/jobControl,
  but few users will have write access there.

- an unset FOAM_JOB_DIR variable is treated as "~/.OpenFOAM/jobControl",
  which can partially reduce environment clutter.

- provide argList::noJobInfo() to conveniently suppress job-info on an
  individual basis for short-running utilities (eg, foamListTimes) to
  avoid unneeded clutter.

- permit SYSTEMMPI user adjustments via
      etc/config.{csh,sh}/mpi-system
  This can be a convenient place for setting up SYSTEMMPI for OpenFOAM
  without adjusting bashrc, prefs.sh ...

- add a USERMPI type. This represents any generic mpi implementation.
  The user is responsible for supplying an appropriate
  wmake/rules/General/mplibUSERMPI file and managing all settings.

  This type of setup can be useful in combination with specific build
  systems (SPACK, EASYBUILD, etc) or module systems for which the MPI
  variant is part of the installed configuration.

- lazier evaluation of project name and version based on the directory
  name. Avoids heuristics based on directory names unless really needed.

- cope with alternative directory locations.
  For example, OpenFOAM+VERSION etc.

The combination of the two above appears to be sufficient to open up
the directory naming possibilities.

- additional -list-test option (tests for existence of directory).

- cleanup variables last in etc/bashrc for a clean exit code

- this allows the sys-admin to provide base values independent of any
  WM_PROJECT_SITE value.

- handle sourcing bashrc with a relative path (issue #383)
- handle sourcing from bash and zsh.
  Still need manual intervention when sourcing dash, sh, or ksh.
- replace grep in etc/cshrc with sed only
- logical instead of physical path for WM_PROJECT_DIR (issue #431).
  Doesn't seem to be possible for csh/tcsh.

  * Continue using physical locations when comparing directories,
    but not for the top-level FOAM_INST_DIR, WM_PROJECT_DIR.

- relocate WM_CC, WM_CXX overrides from etc/config.*/compiler
  to etc/config.*/settings to ensure that they are left untouched
  when etc/config.sh/compiler is sourced while making third-party
  packages (eg, gcc, llvm, CGAL).

- provide fallback FOAM_TUTORIALS setting in RunFunctions

STYLE: remove "~OpenFOAM" fallback as being too rare, non-obvious

- easier to test or use different versions

- change WM_CXXFLAGS to -std=c++11 instead of -std=c++0x

Can now use this:
    _foamSourceEtc config.sh/scotch
    _foamSourceEtc config.csh/scotch

instead of this:
    _foamSource $($WM_PROJECT_DIR/bin/foamEtcFile config.sh/scotch)
    _foamSource `$WM_PROJECT_DIR/bin/foamEtcFile config.csh/scotch`

In the bash/sh version, leave the _foamSource function for now, since
ThirdParty is still relying on it.

STYLE: elminate while-loop for _foamAddPath etc since this type of
construct isn't readily possible for csh and isn't being used anywhere.

- as per bashrc,cshrc delimit with
      "# USER EDITABLE PART"
      "# END OF (NORMAL) USER EDITABLE PART"

  this can help simplify any patching for system-building scripts etc.

- bump ADIOS version to 1.11.1

- makes it easier to switch between mpi implementations (eg, openmpi, intelmpi etc)

- add comment about compiler setting for KNL

- LD_LIBRARY_PATH was not being cleaned at all when switching between
  paraview versions.

- PATH was cleaned against the third-party paraview-*, although 3rd
  party paraview is installed as ParaView-*.
  The additional cleanup for ParaView_DIR may not catch this (if it
  was unset elsewhere).

- wm32/wm64 were for changing between -m32, -m64 builds on x86_64
  architectures. This is seldom enough not to warrant a special alias.
  Also ambiguous if these could refer to label sizes.

- Remove wm32,wm64 aliases.
- Add wmInt32, wmInt64 aliases for switching WM_LABEL_SIZE.

- fixed library path for VTK.
  They should use lib/ and not lib64/

- sometimes used for off-screen rendering.
  Only add to library-path when they are actually available

- the configuration settings can be used for the third-party build,
  but the configuration is not yet actively enabled in
  etc/bashrc, etc/cshrc

which provided warning about backward-compatibility issue with setting div
schemes for steady-state.  It caused confusion by generating incorrect warning
messages for compressible cases for which the 'bounded' should NOT be applied to
the 'div(phid,p)'.

Resolves request http://bugs.openfoam.org/view.php?id=2367

- newer versions of paraview build fine, and so do the reader modules,
  but the reader modules won't load (need to upgrade the classes).
