Adding new features into the quasi-Newton solver

The quasi-Newton solver for dense linear algebra is outdated, i.e., missing some important features which have been implemented and tested in the full Newton solver for the sparse linear algebra.
- check the initialization, i.e., process bounds
- outer iterative refinement (via BiCG)
- second order correction
- switch between fast and stable computation mode
- feasibility restoration
- code style
