The modified definition avoids warnings caused by redundant semicolons.
Now a semicolon is required when using the macro, so a few code locations
had to be updated.

Instrumented code throws this runtime error during OCR:
../../src/api/baseapi.cpp:1616:5: runtime error: load of value 128,
which is not a valid value for type 'bool'
../../src/api/baseapi.cpp:1627:5: runtime error: load of value 128,
which is not a valid value for type 'bool'
If there is no font information (typical for Tesseract with a LSTM model),
the font attributes got random values resulting in wrong hOCR output.

isspace() must only used with an unsigned char or EOF argument,
and even then its result can depend on the current locale settings.
While this is not a problem for C/C++ executables which use the default
"C" locale, it becomes a problem when the Tesseract API is called from
languages like Python or Java which don't use the "C" locale.
By calling isasci() before calling isspace() this uncertainty can be
avoided, because any locale will hopefully give identical results for
the basic ASCII character set.

Instead of adding an empty TBOX at the end of the box list,
that corner case is now handled by passing a nullptr (like
it was already done for the first box in the list).
This avoids the calls of BoxMissMetric with a TBOX
which raises an assertion there (b == 0).

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.

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.
