6ffb53f815 win32: Show TIFF errors on console
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.

26bfd2b9d3 Allow orientation detection with any traineddata
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.

91c7504a35 Added a feature to enrich the hOCR output with glyph confidences
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.

c1c87d73ee Require tesseract/ for API header files (fixes potential name conflicts)
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.

3292484f67 Test for correct locale settings
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.
