The configuration file lstm.train causes Tesseract to generate
training data for training of an LSTM line recognizer.
In this mode, no other files with OCR results should be written.
Without this patch, Tesseract writes a small text file.

This allows OCR of images from the internet without downloading them first:
tesseract http://IMAGE_URL OUTPUT ...
It uses libcurl.

- Use C++ type casts
- Remove unneeded type cast
- Simplify code for function pop
- Remove macro push_on (it was only used once)
This fixes lots of compiler warnings caused by old type casts.
- Use C++ enums
- Use strongly typed C++11 enum for DIRECTION and optimize struct MFEDGEPT
- Use float constant for MF_SCALE_FACTOR
- Replace macros by inline functions
- Fix documentation comment
This fixes several warnings from clang.

Replace the macros which were declared in vecfuncs.h by member functions
and move a function which was only used in chop.cpp to that file.

Removing STRING from genericvector.h allows eliminating the proprietary
STRING data type from the public Tesseract API.

- add another constructor for LSTMRecognizer
which takes the language_data_path_prefix configured/selected
at runtime and passes it to the internal CCUtil
- use this in Tesseract::init_tesseract_lang_data when LSTMs
are available
(this was missing from 297d7d86ce)
