- introduce WM_COMPILE_CONTROL variable to convey control information
  into the build rules.

  The convention (as per spack):
      - '+' to select a feature
      - '~' to deselect a feature

  Eg, to select the gold linker, and disable openmp
  (spaces are not required):

      WM_COMPILE_CONTROL="+gold ~openmp"

CONFIG: accept FOAM_EXTRA_LDFLAGS for AMD, gold, Mingw linkers

CONFIG: generalize PROJECT_LIBS (-ldl used almost universally)

Based on the principles, algorithms, data structures and notation
presented in the book:

    Featherstone, R. (2008).
    Rigid body dynamics algorithms.
    Springer.

This reverts commit e4c14096.

- Rewrote globalPoints to use globalIndex class so now only transfers
single label instead of labelPair
- Added addressing in globalMeshData
    - from coupled master points to slave points
    -         ,,          edges     ,,    edges
    - from coupled points (master or slave) to uncoupled boundary faces
    -               ,,                    ,,                      cells
- See test/globalMeshData for simple test
