e0fc4f2945 Remove opencl_device_selection.h 
Always use OpenCL device selection if OpenCL is enabled.

This fixes a regression which was introduced by commit
5c6a57b727 which removed
the definition for USE_DEVICE_SELECTION.

f0a4d04187 Add config variable for selection of dot product function 
All also a C++ implementation with more aggressive compiler options
which is optimized for the CPU where the software was built.

It is now possible to select the function used for the dot product
with -c dotproduct=FUNCTION where FUNCTION can be one of those values:

* auto      selection based on detected hardware (default)
* generic   C++ code with default compiler options
* native    C++ code optimized for build host
* avx       optimized code for AVX
* sse       optimized code for SSE

d75ef80f12 Get sorted list of available languages 
TessBaseAPI::GetAvailableLanguagesAsVector returned the list of languages
without sorting, so the result was random and not user friendly.
