Merge branch 'stefano_zampini/fix-tao-update-ctx' [PR #1443]
* stefano_zampini/fix-tao-update-ctx:
Few small fixes to Tao before the release.
- TAOSetUpdate: change the Update callback
In SNES, the update function does not uses contexts, and thus it does not appear in the callback prototype.
With TAO, since we are explcitily passing the ctx via TAOSetUpdate, we have to give it back to the user when performing the call
- Tao: PETSc does not print warnings
- MatAssembled: there's no point in checking the type
a matrix with type not set cannot be assembled
- TaoBNKEstimateActiveSet: Call MatHasOperation() only if the matrix has been assembled
the previous logic for MatGetDiagonal still holds. With this fix, the code will not error in case the hessian has not been assembled at this time
