Showing them in a window (default) is not acceptable for a console
application like Tesseract which must be able to work in batch mode.
Such error messages can be triggered by TIFF files which include
vendor specific tags.

While orientation and script detection (OSD) normally requires
osd.traineddata to detect both, it must also be possible to do
only orientation detection with eng.traineddata or any other
traineddata.
Enforce osd.traineddata only if there was no `-l` command line option.
Commit 27ce472666 was too restrictive.

The parameter glyph_confidences is changed from bool to int.
An execution with value 1 outputs the hOCR file enriched with glyph confidences
for every timestep like before. An execution with value 2 outputs the timesteps
accumulated over the recognized characters.

Page segmentation mode "OSD only" requires osd.traineddata,
so use it automatically.
Report a warning if the user specified a different language.

By using the parameter -c glyph_confidences=true the user is able to enrich
the hOCR output with additional information. Tesseract then lists additionally
the timesteps with all glyphs that were considered with their confidence
for every timestep of the LSTM.
The format of the hOCR output is slightly changed: There is now a linebreak
after every word for better readability by humans.

Instead of defining the DISABLED_LEGACY_ENGINE macro in config_auto.h
(which is not included by all source files), define it as a preprocessor
option for those parts of the code which require it.

The division was made with integers, giving a wrong result.
* Avoid division and use pure integer operations.
* Add missing "static" attribute.
