The title can be set for hOCR and PDF output.
Currently it is also used for ALTO, so setting the title can be used
as a workaround for issue #2700.
The constant unknown_title_ is no longer needed and therefore removed.

The function derives the file name for the .box file from an image name.
For training from existing line images, it is useful to directly support
the image names which are commonly used.
While generated images for Tesseract training typically use the name
pattern NAME.tif, other ground truth sets use NAME.bin.png for binarized
or NAME.nrm.png for grayscale images.
BoxFileName is also now a local function as it is only used locally.

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.
