158c845228 Catch another FP division by 0 (fixes issue #3483)

and fixes the division by 0.

Add --reset_learning_rate option to lstmtraining (#3470) 
When the --reset_learning_rate option is specified,
it resets the learning rate stored in each layer of the network
loaded with --continue_from to the value specified by the --learning_rate option.
If checkpoint is available, it does nothing.

c24538518c ThresholdMethod::TiledSauvola -> ThresholdMethod::Sauvola 
The fact that this method uses tiles is implementation detail. It does not change the result compared to Sauvola without tiles. The use of tiles minimize memory consumption.

422452b9f4 Check for float errors when running tesseract and lstmtraining 
Some illegal floating point calculations like division by zero,
illegal value or overflow will now abort tesseract with an error
message.

For lstmtraining there is now a new parameter --debug_float to
enable the same kind of checks. It is currently disabled by default
because such errors occur and would abort the training process.
That should be fixed in the future.
