Summary 0000974: SQP improvements
Description * We need GammaMax in the new FSQP! rejected steps MUST contribute to GammaMax. We also need a special return code 99 which is intended for a situation when GammaMax is suspiciously large.

* We also need a positive completion code for a solver trapped in a nonzero constraint extremum.

* filter SQP has issues when starting from a local maximum of a constraints violation, like minnlc_d_equality with x0=[0,0]. An SL1QP is better, but adding L1 merit function is likely to overcomplicate the algo.
