- a top-level cloud::nParcels() virtual, which is overloaded by the
  first level of Cloud inheritance. This permits quick determination of
  cloud sizes, even when retrieved from registry with the base level.
  Eg,
      cloud* cldPtr = mesh.cfindObject<cloud>("myCloud");
      label nParcels = (cldPtr ? cldPtr->nParcels() : 0);

- make writeLagrangianPositions on by default unless explicitly
  disabled in the InfoSwitches.

  Flag output errors (where neither coordinates nor positions are
  written) with Fatal.

- additional IOField helper functions in cloud

STYLE: simplify iterator inheritance

- these use the additional byte-size checks in IOstream to handle
  native vs non-native sizes

- creates a dummy time, which is useful when a local object registry
  is needed

- can now specify literal matches for sub-dictionary methods:

    isDict(key, keyType::REGEX)
    optionalSubDict(key, keyType::REGEX)
    subDict(key, keyType::REGEX)
    subOrEmptyDict(key, keyType::REGEX, mandatory)

There is no change in behaviour of the methods, just the search option
is now exposed as an optional parameter.

NOTE: minor breaking change for subOrEmptyDict()

  old: subOrEmptyDict(key, bool=false)
  new: subOrEmptyDict(key, keyType::option=keyType::REGEX, bool=false)

  This affects code that previously explicitly set the bool parameter.
  Within OpenFOAM itself, this only affected a single file:

      KinematicCloud.C

- this is principally for cases where reduced indentation is desired,
  such as when streaming to a memory location. If the indentation size
  is zero or one, only a single space will be used to separate the
  key/value.

  This change does not affect the stream allocation size, since the
  extra data falls within the padding.

ENH: relocate label/scalar sizes from Istream to IOstream.

- could allow future use for output streams as well?

  Due to padding, reorganization has no effect on allocated size
  of output streams.

STYLE: add read/write name qualifier to beginRaw, endRaw

- removes ambiguity for bi-directional streams

STYLE: fix inconsistent 'const' qualifier on std::streamsize

- base Ostream was without const, some derived streams with const

- allows full recovery of allocated space, not just addressable range.

  This can be particularly useful for code patterns that repeatedly
  reuse the same buffer space. For example,

      DynamicList<char> buf(1024);

      // some loop
      {
          OListStream os(std::move(buf));
          os << ...

          os.swap(buf);
      }

   Can read back from this buffer as a second operation:

      {
          UIListStream is(buf);
          is >> ...
      }

- data types were used for initial adios interface, but this proved
  difficult to manage and maintain.

- 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
