bd13069fe8 Simplify class LSTMTrainer 
The function pointers and callbacks file_reader_, file_writer_,
checkpointer_reader_ and checkpoint_writer_ are always set to
the same values. Replacing them by direct function calls
simplifies the code and allows removing more code from tesscallback.h.

3871caae86 Simplify indirect call of LMPainPoints::GeneratePainPoint 
It does neither need a temporary TessResultCallback2 nor the function
LMPainPoints::GenerateForBlamer.

This also allows removing more code from tesscallback.h.
