- foamCleanPath now only splits the environment variable on ':', which
  allows other directories with spaces or '(..)' etc to pass through
  without major issue.

- The filter arguments are split on whitespace, colons or semi-colons.

- ADIOS 1.13.0
- fftw 3.3.7
- paraview 5.4.1

ENH: include ThirdParty QT libraries in LD_LIBRARY_PATH for paraview

- also handle stray semi-colons in foamCleanPath.
  Treat like a ':' separator.
  They are incorrect and potentially problematic for shell evals.

- export library path for gmp/mpfr from CGAL config files.
  This is required when non-system gmp/mpfr libraries are being
  used, but not using a ThirdParty compiler installation.

- automatically handle lib/ vs lib64/ (eg, for central installations)
  for packages such as boost, CGAL, etc. While the ThirdParty
  compilation of these will normally land in lib64/, this may not be
  the case when they are supplied by another means.

- reworked the handling of foamEtcFile and foamCleanPath for less
  clutter in the configuration files.
  Added the bin/tools/lib-dir script to handle logic that is
  too complex to easily manage in csh.

- unknown options or missing option values now emit a shorter message
  without the entire usage. This makes it easier to identify the errors
  and is better aligned with the behaviour of GNU system tools.

  ====
     $ simpleFoam -case
     Using: OpenFOAM-plus (see www.OpenFOAM.com)
     Build: plus-01234

     Error: option '-case' requires an argument

     See 'simpleFoam -help' for usage
  ====

- provide for reduced (-help) and full (-help-full) usage information.
  In many cases the reduced usage provided sufficient and easier
  to find the information.

- make -srcDoc an alias for -doc-source

- no warnings about option aliases for future dates.

- Can occur with some user names, or mounted paths.
  Resolve by using '?' for the separation character.

  Since '?' is a shell-glob, it is highly unlikely to occur appear in
  filenames.  Additionally, it is not a meta-character in standard sed,
  nor in the GNU extension (which uses '\?').

- also split on colons for consistency

This reverts commit c5bea524.

This reverts commit 2e1e671d.

- the path is accesible either way, but use setenv for consistency with
  other environment variables. It also simplifies foamCleanPath again.

- this allows more direct use by c-shell

- Also adjusted formatting of usage to match what argList generates

- old-style (left untouched for now):
  app, lib, run, sol, tut, util

- new-style:
  foamApps, foamLib, foamRun, foamSol, foamTut, foamUtils

- additional aliases:
  userApps, whichFoam

NB: ideally we'd have 'foamSrc' instead of 'src'.
    Do we really need 'foamsrc' and 'foamfv' anyhow?

The call to foamCleanPath from etc/{bashrc,cshrc} passes all the wildcards
together as a single argument - causing nothing to be cleaned.  Now split
the args on whitespace. Also added more IFS hacking to reduce forking.
