Fixes to mode_compute=5. (1) force univariate steps at every iteration: improve robustness at the expenses of a bit less efficiency; (2) fix gradient computation for special cases when the value of the parameters get stacked at the prior boundary.

mr_gstep, mr_hessian: fix Octave compatibility issue
...
These functions were saving the whole workspace (with a "save" command). This
workspace includes a function handle which Octave does not know how to save.
The quick fix was to remove these "save", since they also harm performance and
are only useful for debugging purposes.
