- for codedFunctionObject and CodedSource the main code snippets
  were not included in the SHA1 calculation, which meant that many
  changes would not be noticed and no new library would be compiled.

  As a workaround, a dummy 'code' entry could be used solely for the
  purposes of generating a SHA1, but this is easily forgotten.

  We now allow tracking of the dynamicCodeContext for the coded
  objects and append to the SHA1 hasher with specific entries.
  This should solve the previous misbehaviour.

  We additionally add information about the ordering of the code
  sections. Suppose we have a coded function object (all code
  segments are optional) with the following:

      codeExecute "";
      codeWrite   #{ Info<< "Called\n"; #};

  which we subsequently change to this:

      codeExecute #{ Info<< "Called\n"; #};
      codeWrite   "";

  If the code strings are simply concatenated together, the SHA1 hashes
  will be identical. We thus 'salt' with their semantic locations,
  choosing tags that are unlikely to occur within the code strings
  themselves.

- simplify the coded templates with constexpr for the SHA1sum
  information.

- Correct the CodedSource to use 'codeConstrain' instead of
  'codeSetValue' for consistency with the underlying functions.

- can be used for outputing sampled surfaces in x3d format for direct
  import in other rendering tools.

All remote contributions to interpolation stencils now
get added as 'processor' type lduInterfaces. This guarantees
a consistent matrix, e.g. initial residual is normalised to 1.

Second change is the normalisation of the interpolation discretisation
which uses the diagonal from the unmodified equation. This helps
GAMG.

- this corresponds more closely to the expected behaviour of a
  patch-average value being independent of the local face
  discretization

- localize some functionality, std::array for digest internals.
  Additional append sub-string methods, pass-through write of digest
  etc.

- only apply component-wise transformCoupleField for non-scalar types

- amalgamate dlSym() and dlSymFound() into a single dlSymFind() backend
  with optional 'required' argument. This makes it possible to
  query and assign at once.

- previously would have different SHA1 depending on whether the
  string was a C-string, a C++-string or if the SHA1 was calculated
  directly or via the OSHA1stream.

    - SHA1("string")
    - OSHA1stream << "string";
    - OSHA1stream << string("string");

  By avoiding string quoting on output, they now all deliver the same
  result. This also means that the following will no longer change the SHA1
  content, since it does not add anything:

    osha<< string() << string() << string() << string();

  This would have previously add a pair of double quotes each time!

- failed when nAlphaSubCycles > 1 and nOuterCorrectors > 1.
  Fixed thanks to Henning Scheufler (DLR Bremen).

- Eg, with surface writers now in surfMesh, there are fewer libraries
  depending on conversion and sampling.

  motion.
