7544164d53 regIOobject, Hasher, IOobject tweak
- regIOobject: don't re-register an unregister object on rename/assignment
- Hasher: split-off HasherInt with uint32_t specializations
- IOobject: writeBanner/writeDivider return Stream for easier chaining.

... also dropped some namespace bracketing while I was at it.

17548296be Switched from old hashing functions to use Bob Jenkins' hash routine
- If the underlying type is contiguous, FixedList hashes its storage directly.
- Drop labelPairHash (non-commutative) from fvMeshDistribute since
  FixedList::Hash does the right thing anyhow.
- Hash<edge> specialization is commutative, without multiplication.
- Hash<triFace> specialization kept multiplication (but now uLabel).
  There's not much point optimizing it, since it's not used much anyhow.

Misc. changes

- added StaticAssert to NamedEnum.H
- label.H / uLabel.H : define FOAM_LABEL_MAX, FOAM_ULABEL_MAX with the
  values finally used for the storage.  These can be useful for pre-processor
  checks elsewhere (although I stopped needing them in the meantime).

44a86232af Added Jenkin's hash functions in C++ form
- not much speed difference between SuperFastHash and Jenkin's lookup3 but
  both are 5-10% faster than what is currently implemented in Foam::string,
  albeit inlining probably helps there.

- TODO: integration with existing infrastructure
