Trust region solver: recompute Jacobian only when necessary
...
Previously, the solver would recompute the Jacobian at every iteration. But, if
an iteration fails, the current point is not moved (only the radius of the
trust region changes), hence it is not necessary to recompute the Jacobian in
that case. This commit implements this optimization.

Use true/false instead of 1/0 for boolean options
...
This is more elegant, and makes it easier to distinguish them from integer
options.
Also simplify test expressions for these boolean options.
