- eases management/control of previously calculated sums
- add empty() member function to SHA1Digest
- adjust Copyright dates

- update packing for FOAM_EXT_LIBBIN and newer FOAM_APPBIN
- pack OpenFOAM source via 'git archive' for consistency with
  the git repository (use -nogit option to revert to manual packing)
- combine foamPackBin + foamPackThirdPartyBin
- add foamPackThirdPartyBinAll (like foamPackBinAll)

- relocate service scripts into bin/tools
- use more standard 'tgz' instead of 'gtgz'

STYLE: minor rewording, drop grep/sed in favour of sed only

- remove settings for really old cmake versions

- place under $WM_THIRD_PARTY_DIR/lib/$WM_OPTIONS
- relocate FOAM_MPI_LIBBIN accordingly

Conflicts:
	src/OpenFOAM/meshes/primitiveShapes/tetrahedron/tetrahedronI.H

All of graph gets sent to master which does the decomposition

eg,
    - makePatchTypeField -> makeTemplatePatchTypeField
    - makeNonTemplatedPatchTypeField -> makePatchTypeField

- avoid non-standard 'tempfile' in bin/tools/foamConfigurePaths

- consistent and shorter naming throughout

- simplifies syncing compiled versions.
  For a runtime environment, only need these directories:
      bin/
      etc/
      lib/

- filter out other subdirs, which could be architecture-specific

- more obvious in its meaning

No warnings on recoverable degeneracies.
