f4698154b3 Revert "Replace callback by direct function calls in TessBaseAPI::GetComponentImages" 
This reverts commit 1a44ce3178.
It removed global symbols, so the binary API was incompatible.

792b39d5c8 Revert "Move LSTMTrainer from libtesseract to libtesseract_training" 
This reverts commit a30d433356.

That commit removed LSTMTrainer also from libtesseract.so which breaks
the ABI compatibility.

1a44ce3178 Replace callback by direct function calls in TessBaseAPI::GetComponentImages 
The new code avoids dynamic memory allocation, uses faster function calls
and allows removing more code from tesscallback.h.

563a1717d4 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.

6a0fc4f89f Simplify indirect call of LMPainPoints::GeneratePainPoint 
It does neither need a temporary TessResultCallback2 nor the function
LMPainPoints::GenerateForBlamer.
