- simplifies things for legacyCompile

- 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.

- With argList::noFunctionObjects() we use the logic added in
  4b933332 (issue #352)

  By removing the '-noFunctionObjects' option, we automatically
  suppress the creation of function-objects via Time (with argList
  as a parameter).
  There is generally no need in these cases for an additional

      runTime.functionObjects().off()  statement

  Use the argList::noFunctionObjects() for more direct configuration
  and reduce unnecessary clutter in the -help information.

  In previous versions, the -noFunctionObjects would have been redundant
  anyhow, so we can also just ignore it now instead.

- the backend script should not be accessible from the PATH.
  Using deprecated/ adds a level of documentation.

- since 1612, FOAM_INST_DIR and foamInstDir longer have any
  special meanings when sourcing the bashrc or cshrc files.
  Thus no need for special treatment in any of the dispatch wrappers.

  Retained FOAM_INST_DIR as (unexported) variable in etc/bashrc,
  just in case people are using patched versions of etc/bashrc
  as part of their installation.

ENH: relax prefix restrictions on foamCreateVideo (issue #904)

- shift the implicit '.' to be part of the default prefix. This allows
  things like "-image myimages_00" to work as might be expected.

- respect trailing '-', '.', '_' for the image prefix name.
  For example,

    -image press_   to accept press_*.png

- additional -mask width option (for avconv)

- The additional output generated by #calc directives in the
  controlDict or decomposeParDict causes issues for the RunFunctions
  extraction of 'application' and 'numberOfSubdomains'.

  Avoid by using -disableFunctionEntries, which also has the side-effect
  of disabling '#include'.

- Don't remove the constant/polyMesh directory if it contains a
  blockMeshDict or blockMeshDict.m4 file. Offer a reminder that
  system/ is the normal place for it.

- add additional control via a Foam::infoDetailLevel flag, which is
  supported by a 'DetailLevel' macro.  Eg,

      DetailLevel << "some information" << nl

- When infoDetailLevel is zero, the stdout for all Foam::system() calls
  are also redirected to stderr to prevent child output from
  appearing on the parent.

- close stdin before exec in system call.

- add support by using updated foamEtcFile from 1806, which also add
  the '-config' short-cut option.

- now report as  "min = XX max = YY average = ZZ"
  instead of as  "min/max/average = XX, YY, ZZ"

  this makes it easier to parse any particular value
  (eg, with foamLog)

- removed some unneeded tutorial files

- include bash completion for paraFoam, and provision for using
  foamEtcFile as well.

- ADIOS 1.13.0
- fftw 3.3.7
- paraview 5.4.1

ENH: include ThirdParty QT libraries in LD_LIBRARY_PATH for paraview

- this makes it possible to use "foamAddCompletion paraFoam" and have
  bash completions for paraFoam as well

- a -valgrind option for logging with valgrind

- determine number of processors from system/decomposeParDict
  or -decomposeParDict if -np was not specified

- generalize some of the library extensions (.so vs .dylib).
  Provide as wmake 'sysFunctions'

- added note about unsupported/incomplete system support

- centralize detection of ThirdParty packages into wmake/ subdirectory
  by providing a series of scripts in the spirit of GNU autoconfig.
  For example,

      have_boost, have_readline, have_scotch, ...

  Each of the `have_<package>` scripts will generally provide the
  following type of functions:

      have_<package>          # detection
      no_<package>            # reset
      echo_<package>          # echoing

  and the following type of variables:

      HAVE_<package>          # unset or 'true'
      <package>_ARCH_PATH     # root for <package>
      <package>_INC_DIR       # include directory for <package>
      <package>_LIB_DIR       # library directory for <package>

  This simplifies the calling scripts:

      if have_metis
      then
          wmake metisDecomp
      fi

  As well as reducing clutter in the corresponding Make/options:

      EXE_INC = \
          -I$(METIS_INC_DIR) \
          -I../decompositionMethods/lnInclude

      LIB_LIBS = \
          -L$(METIS_LIB_DIR) -lmetis

  Any additional modifications (platform-specific or for an external build
  system) can now be made centrally.

- affected csh users

- now uses current OpenFOAM code level

- added initial catalyst script for insitu processing of overset

- now replaced 'if ! isTest' with 'if notTest' for most cases.

- sentinel was not working properly when building user-space routines

- forward command-line arguments for paraview, where they may also be
  evaluated (cshrc, POSIX shell)
  Eg,
      . etc/bashrc ParaView_VERSION=5.4.1-mpipy
      source etc/cshrc ParaView_VERSION=5.4.1-mpipy

- 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.

- for tutorials that are known to run poorly, can provide a
  placeholder Allrun-optional instead of the usual Allrun script.
  If this is detected, the case will be skipped.

- support when creating modules for OpenFOAM.
