Does not fix the tolerance issue.

- now maintains a correct list of geometry instances, without assuming
  contiguous file numbering. However, if the numbering is contiguous,
  the more compact case representation will be used.

- an advanced feature, for example when sampling on a static patch
  while some motion occurs elsewhere. [use with caution]

- If the sampled surface dictionary is modified during run-time, the
  ensight file indexing for the geometry will become out of sync.
  This is addressed in a subsequent commit.

- this can be useful for preloading of libraries, or for utilities
  that don't use system/controlDict.

  The additional libraries can be specified individually:

      myUtil -lib lib1 -lib lib2 -lib lib3

  When specified like this, the options add up.

  Or as a 'captured' list using OpenFOAM's standard arg list handling:

      myUtil -lib '(' lib1  lib2 lib3 ')'
      myUtil -lib \( lib1  lib2 lib3 \)

  or as single argument list:

      myUtil -lib '("lib1" "lib2" "lib3")'

  When specified as a single argument, would normally take advantage
  of the transparent handling of word vs fileName and omit the string
  quotes:

      myUtil -lib '(lib1 lib2 lib3)'

ENH: dlOpen error messages now propagated into dlLibraryTable

- this makes the context more relevant and also avoids the previous
  annoyance of double warnings (one from the POSIX loader, and one
  from dlLibraryTable)

STYLE: mark -noFunctionObjects and -withFunctionObjects as 'advanced'

- reduces clutter. Still visible with -help-full

- include ragel and lemon

- rename pre-generated files to ".cc" so that they are more
  recognizable as being different from regular file content.

- should have been part of commit 9d36d3c0
  which allows us to upcast a word to a fileName.

- allows direct reading of a single entry with token checking

- add additional rule (ending '.ll') for the combination of
  flex for C-code but compiling the result as C++.
  This can be needed for re-entrant parsers.

- update bison rule to handle renaming of skeleton files.
  Use a wrap-bison script to manage this.

- alternatively can use uniformNormalFixedValue with PatchFunction1
  specification and temporal ramping.

TUT: add ramped example for simpleCar

- This improves consistency for warnAboutAge and build information
  when the API level changes

- compacter messages in some cases

STYLE: simplify output handling of line numbers

- relax casting rules
  * down-cast of labelToken to boolToken
  * up-cast of wordToken to stringToken.
    Can use isStringType() test for word or string types

- simplify constructors, move construct etc.

- expose reset() method as public, which resets to UNDEFINED and
  clears allocated storage etc.

DEFEATURE: remove assign from word or string pointer.

- This was deprecated 2017-11 and now removed.
  For this type of content transfer, move assignment should be used
  instead of stealing pointers.

- makes its use somewhat clearer and allows more future options

- new patches were added to the end of existing patches, which placed
  them _after_ the processor patches. This is incorrect.
