- do not enable function objects by default if there is no means of
  disabling them.

This helps on bounding Twall on cases where large inertia is found in the first cell
next to the fluid (i.e large cell, rho or Cp)

Improvements, adjustments for build scripts and infrastructure

See merge request !94

- new behaviour is to do nothing if no platform was specified.
  This helps avoid inadvertently removing files.

- support special platforms for compatibility with wmake/wclean targets.
  Eg, "wcleanPlatform all"

- allow use from ThirdParty top-level as well, since the directory
  structure is similar.

BUG: fix regression in wcleanLnIncludeAll introduced by 9e2e1115

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.

- Eg, instead

      if file=$(foamEtcFile filename)
      then
          . $file
      fi

  can write

      eval "$(foamEtcFile -sh filename)"

  Also supports -verbose reporting, which is especially useful for csh,
  since it allows simplification of aliases and allows the message to
  land on stderr instead of stdout.

      eval `foamEtcFile -csh -verbose filename`

STYLE: improve consistency in Allwclean scripts

- this may still need more testing, but the basic idea is to find
  directories with 'Allwclean' or 'Make' and process them (once!)

- use -name test before -type test to avoid calling stat(2) on every file.
- use -delete instead of -exec rm to avoid forking

- remove some spurious regExp includes

Flat list output

See merge request !93

- 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

For certain combinations of rays and triangles the fast bb-triangle intersection
routine is not correct. For now revert to slow edge-by-edge intersection.

- makes it slightly easier when packaging various binaries, or when
  building packages for installation via modules etc.

- reduces unexpected interactions between various make elements

BUG: noise - updated creation of control dictionary to allow -case option and env variables.  Fixes #402

- The dirToString -strip option is simple, but reduces effort for the caller.

- also add some comments about the side-effects

- For convenience, let "wmake some/path/filename.C"
  behave similar to    "wmake some/path"
  and trace back for the Make directory.

- Introduce writeList(Ostream&, label) method in various List classes to
  provide more flexibility and avoid hard-coded limits when deciding if a
  list is too long and should be broken up into multiple lines (ASCII only).

- The old hard-code limit (10) is retained in the operator<< versions

- This functionality is wrapped in the FlatOutput output adapter class
  and directly accessible via the 'flatOutput()' function.

Eg,
    #include "ListOps.H"
    Info<< "methods: " << flatOutput(myLongList) << endl;

    // OR

    Info<< "methods: ";
    myLongList.writeList(os) << endl;

- templated code that is not actually be used yet.

ENH: avoid combineFields for serial case

Note: a 'master-only' variant with combineList only on the master and
without scatter can be pursued later.

- either (or both) of 0/, 0.orig/ may exist, so error messages about
  one of them being missing is a bit misleading

- collects the log information only, without running any cases.
  This can be useful if the user has terminated the test prematurely
  but nonetheless wishes to summarize the log output.

- constness on local variables, pre-increment on loops, parameter names
