- When building OpenFOAM for different platform combinations
  (single/double, int32/int64) the build information that is compiled
  into the OpenFOAM lib can become out of sync.

  This is because the update trigger (wmakeBuildInfo -check) is
  independent of the targetted platform. The added file
  'src/OpenFOAM/Alltouch' provides a direct means of forcing a rebuild
  of the version information. Eg,

      src/OpenFOAM/Alltouch
      wmake src/OpenFOAM

  Also provide an additional 'wmakeBuildInfo -remove' to forcibly
  remove META-INFO/build-info, if that is desired.

- use readBegin() when the only delimiters are '()' and not '({})'

- symmetric with writeRaw() etc for the output stream. These are
  methods that are not required by normal users, but which provide
  a finer granularity for reading.

- additional information about the current stream position when
  endList fails. This may help when tracing errors.

STYLE: change return type of beginRaw()/endRaw() to bool

- was of type Ostream& for output, but return value was unused.
  Having bool may be better for encapsulating logic

STYLE: remove unused Istream::readEndBegin() function

- in InterfaceCompositionPhaseChangePhaseSystem, the mass transfer
  rates are updated as a side-effect of the massTransfer() method,
  which makes these fields non-const.

- only prefix 'lib' for names without a path

STYLE: add more OSspecific debug output for library loading

- adapted openfoam.org code.  Original commit message:

  Instead of adapting tet base points cell-by-cell, the dangling
  points are pre-computed and then the adaptations to the base points
  are made face-by-face. This correctly adapts faces which have
  different dangling points relative to the owner and neighbour cells.

- treat the faces that would be exposed on a subset as boundary faces
  for the erosion algorithm

STYLE: adjust code for consistency between isoSurfaceCell and isoSurfaceTopo

- previously only had "regularise" as a bool value, now support
  enumerations too

- add patch-point tracking to structured walk

- provision for cylindrical interpolation scheme

STYLE: more efficient use of bitSet

- return Ostream&
- make header separation optional

- empty(), size(), toc(), sortedToc()

- makes the standard config variables more visible

- add an 'isoAlgorithm' keyword to distance surface and cutting plane
  to advance further testing of the isoSurfaceTopo algorithm.

  Does not yet handle the full spectrum of bound boxes, cellZones etc.

- to simplify/unify error handling

STYLE: use NotImplemented instead of longer notImplemented(...)

- unfriend HashSet, HashTable IO operators

- global min(), max(), minMax() functions taking a labelHashSet and an
  optional limit. For example,

      labelHashSet set = ...;

      Info<< "min is " << min(set) << nl;
      Info<< "max (non-negative) " << max(set, 0) << nl;

- make HashTable iterator '->' dereferencing more consistent by also
  supporting non-pointer types as well.

- read HashTable values in-situ to avoid copying

- the Enum::readEntry() method was previously as bit sloppy with
  respect to the enumeration that it accepted. If the input was
  non-mandatory, typos would go unnoticed. Now tighten things so that
  if an enumeration is found, it must also be valid.

STYLE: remove unused/deprecated Enum::lookupOrFailsafe() method

- this was only used in a few places internally in 1712 and 1806 but
  has since then been superseded by getOrDefault() with an optional
  'failsafe' flag.

- previously deprecated and slated for removal in 2018-03

- add triSurface::subsetMesh single-parameter variant
