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.

The tesseract/ subdirectory is no longer automatically added to the
include path of the compiler. Therefore old code which used code like
#include "capi.h"
must now change that to
#include "tesseract/capi.h"
This avoids name conflicts with header files from other projects.

Commit 87d33b6c9e added code which uses bool.
Therefore stdbool.h must be included for compilations with a C compiler.

Normal C++ programs like those which are built for tesseract automatically
set the locale "C".
There can be different locale settings if the tesseract library is used
in other software.
A wrong locale can cause wrong results from sscanf which is used at
different places in the tesseract code, so make sure that we have the
right locale settings and fail if that is not the case.

The C API is missing the ability to monitor the progress of the
recognition. This patch adds C wrappers to the progress monitor
that allow monitoring the progress and canceling the recognition
process early.
The commit effa574 in 20.01.2017 added the bool textonly to the constructor of TessPDFRenderer. To maintain the compatibility to older APIs which are still using only two parameter, a default value for the textonly parameter is set.
