- 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

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

- reduces unexpected interactions between various make elements

- 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.

Flat list output

See merge request !93

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.

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

- 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

- outputs compound tags etc.
  Should only be called by itself or by a derived class.

- fast means of ensuring we are only testing what is contained in the
  repository
