Some fixes for openmp in class residual.

Several algorithms and implementations for hessian calculation.

Fixes for the features introduced in 635cc476 in the case USE_OMP was
not activated in cmake.

Cleanup of Row class and Matrix class.

Significantly reduced memory required for Row class and consequently for
multivar_expression class. Moved out openmp locks and row annotation as
additional service classes.

Introduced classes HessianRow and HessianMatrix for future possibility
of hessian computation in automatic differentiation.

Changed how matrix annotation is handled to decrease memory required to
store data of type DATA_VARIABLE.

Added multivar_expression_reference that can reference individual matrix
row.

Added Residual class.

Fixed that Sparse::Matrix::Load and Sparse::Vector::Load may required
MPI initialization.

Fix for possibility of race condition in point-to-point MPI
communications.

Fixes for warnings produced by clang.

Fixes for GCC.

Moved functionality to operate with dense matrices as INMOST service.

Added possibility to exchange data of type DATA_VARIABLE in parallel.

Added possibility to include external content in xml format.

Moved overloaded operators for variables from namespace INMOST into
global scope to prevent possible ambiguities in compilers.

Added perturbation algorithm for BCGS solver.
