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

must now change that to

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.

e254c9fa38 Return a value from default progress report function 
The progress reporting function returns a boolean. The returned
value is never used by the tesseract and its meaing is not
documented, which renders the value meaningless. Still, lack of
return should not be premitted.

87d33b6c9e Add progress monitoring C api 
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.

217e5e5881 Add a context-aware progress monitor pointer 
The progress_callback field in the ETEXT_DESC monitor type does not
take any 'context' parameter, which may make implementing callback
functions difficult and may require use of global variables.
The new function receives the ETEXT_DESC pointer as an argument.
This makes it possible to share the cancel_this field as context
carrier if required.
The change is backwards-compatible: the old pointer remains as a
member of the class, and the default value for the new pointer is
a function calling the classic progress notifier. This way the code
unaware of the new member will continue to work as before.
