Add block preconditioners to be used in LinearDifferentiableBlockSolver. This includes block diagonal (additive fieldsplit), block triangular (multiplicative fieldsplit) for arbitrary N x N block systems, as well as Schur complement factorizations for 2x2 systems, with a standard Schur complement approximation (selfp).
