A first attempt, just to get started

https://github.com/josef-pkt/scipy/commit/548a8925c36c2627f0acb8102a835393deeefe26

in optimization, do we drop the disp option for warnings and the
associated prints ? there still remains the final print for success.

Is there a way to set the default warning level for the UserWarning to
"always" ?

Still needs tests, examples that raise the warnings.

(I'm only partially familiar with the internal details of
scipy.optimize, interpolate, ... )
