This reverts commit 102f7970.

ENH: report line number for illegal words and for copyrights

- allows fixes before trying to push

- findAll() method returns a labelList of all matching names
- find() method returns the index to the first matching name

  For example, use a regex to specify alternative coordinate systems
  in porousZones
  (
      "cat1?(Back|Front)*"
      {
          coordinateSystem    "(cat1|system_10)";
          porosity    0.781;
          ...
      }
  )

- allows a regex to collect several cellZones.
  For example,
  (
      "cat1?(Back|Front)*"
      {
          coordinateSystem    system_10;
          porosity    0.781;
          ...
      }
  )

Adapted meshSearch and sampledTriSurfaceMesh to use it.

- makes it easier to cut-and-paste from dictionary contents that use
  the Foam::findEtcFile expansion

- as per commit 937e0d23
