James R. Barlow bc95798e01 Implement a new orientation and script detection API for C and C++
See issue #424.

The existing C API for TessBaseAPIDetectOS requires a C caller to successfully allocate struct OSResults which is actually a C++ class.  Generally it won't
be possible for a regular C compiler to do this properly.

It's also assumed that most API level users of Tesseract are only interested in Tesseract's best guess as to script and orientation, not the individual values for all possible scripts.

This introduces a new API with a better name that is more closely aligned with the output of 'tesseract -psm 0'.  Both tesseract -psm 0 and this API now share the same code in baseapi.cpp.
