1cf8fe51a0 Remove mathfix.h 
It was only needed for MS Visual Studio 2012 and older.
Those compilers are not supported for Tesseract.

5f8ecdb2b3 Remove local implementation of strtok_r 
MS Visual Studio does not provide that function, but can use strtok_s
which does exactly the same.

44a5e3da40 Update from Leptonica 1.74.1 to 1.74.2 
The newer version contains fixes for the pixUnsharpMaskingGray*
functions which are relevant for Tesseract (used in ImageData::PreScale
which calls pixScale).

34d1e7331d LSTMTrainer: Catch empty vectors 
The new test in LSTMTrainer::UpdateErrorGraph fixes an assertion
(see issues #644, #792).

The new test in LSTMTrainer::ReadTrainingDump was added to improve
the robustness of the code.

Optimize LSTM code for builds without OpenMP

15b3596ec4 Optimize LSTM code for builds without OpenMP 
The constant value kNumThreads is not only used to configure the number
of threads but also to allocate vectors used in those threads.

There is only a single thread without OpenMP, so it is sufficient to
allocate vectors with only one element in that case.

Replace also the upper limit in the for loops by the known vector size.
