There is a bug in the early stop callback function #3938 when eval.metric needs to be maximized. The mx.callback.early.stop as soon as the evaluation increases even when the "maximize" is set to TRUE.

The line 138 of R-package/R/callback.R must be changed from

if (result$value > mx.best.score | (maximize == TRUE & result$value < mx.best.score)) {

to

if ((maximize == FALSE & result$value > mx.best.score) | (maximize == TRUE & result$value < mx.best.score)) {

Most of the fixes should be self evident. For tutorial on pre-trained models, one of the images doesn't exist anymore so selected a new one. Long-term, we should put such images on web-data repo but alas, some other day.

For Handwritten digit tutorial, we are missing couple of imports in the test_utils.py that was recently created.

Note that: for pre-trained model tutorial, we get a softmax_label warning and the probability scores are not really probabilities. Will deal with that issue in another PR.

Testing:
I've tried to test all the notebooks with this change and things look fine.

1. In the notes section for ndarray, references did not seem clear enough to be referring to mxnet.ndarray or numpy.ndarray. Added the package names as prefixes to make it more obvious.
2. "share the same C++ operator source codes" => "share the same code". Since we don't really need to throw in more details than required.
3. Other relatively  minor language changes which will be obvious from the diff.

Note that I'm relatively not sure about the need for 1/ since it makes things more verbose. Let me know if it unnecessary and I'll remove it.
