db9c7e0312 Use std::stringstream to generate hOCR output
Using std::stringstream simplifies the code and allows conversion of
double to string independant of the current locale setting.

1f5fb15af3 remove setting constant resolution from ImageThresholder::SetImage.
Credible resolution with be set afterward. Fixes #2080.

fbbbdb4565 Use std::stringstream to generate ALTO output and add <SP> element
Using std::stringstream simplifies the code.
The <SP> element is needed between two >String> elements.
Remove also some unneeded spaces in the ALTO output.

Fix two runtime errors

c9e85ab78f Fix wrong font attributes in hOCR output
Instrumented code throws this runtime error during OCR:

    ../../src/api/baseapi.cpp:1616:5: runtime error: load of value 128,
      which is not a valid value for type 'bool'
    ../../src/api/baseapi.cpp:1627:5: runtime error: load of value 128,
      which is not a valid value for type 'bool'

If there is no font information (typical for Tesseract with a LSTM model),
the font attributes got random values resulting in wrong hOCR output.

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
