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.

When Tesseract is called without any argument, the help message is still
printed, but the exit status no longer indicates success (EXIT_OK).

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.
