534a237015 Move AVX / SSE messages to function PrintVersionInfo (crash fix)
This information is not needed for normal runs, so it is sufficient
to show it on request (like versions and OpenCL information).

This also fixes a crash caused by undefined order of global constructors:

When the global variable SIMDDetect::detector is initialized before the
global variable debug_file, the first tprintf call in simddetect.cpp
crashes because of a NULL pointer in debug_file. This was only seen when
running with a shared library (libtesseract.so).

19616b07ba lstm: Move class SIMDDetect to new source file and improve code
Modify also the code to use a singleton. This simplifies the code as
no locking is needed. It also slightly improves the performance because
no check whether the architecture was tested is needed.

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.

Builds without support for OpenMP failed with the old code. Fix this:

* Always use _OPENMP for conditional compilation.
* Remove OPENMP as there is already _OPENMP.
* Include omp.h conditionally.
