Multiple sparse linear algebra backends.

1. Added support for CXSparse - SparseNormalCholesky and
   SchurComplementSolver support SuiteSparse and CXSparse now.
   I am not sure I will add suport for visibility based
   preconditioning using CXSparse. Its not a high priority.

2. New enum SparseLinearAlgebraLibraryType which allows the user
   to indicate which sparse linear algebra library should be used.

3. Updated tests for SolverImpl and system_test.

4. Build system changes to automatically detect CXSparse and
   link to it by default -- just like SuiteSparse.

5. Minor bug fixes dealing in the cmake files and VBP.

6. Changed the order of the system test.

7. Deduped the unsymmetric linear solver test.
