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.
Commit 0248c7ff9d replaced math.h by cmath.
Therefore isinf and isnan are no longer declared.
Replace them by their C++ 11 variant.

As the "register" keyword is now no longer used by the Tesseract code,
the compiler option -Wno-error=deprecated-register can be removed.
