a1e3150bd7 Add new parameter "document_title" to set the title in OCR output files 
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.

7a7704bc94 Extend function BoxFileName to handle more common image names 
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.

1e84a6f225 Don't create OCR result files when training data is created 
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.

5fa09f184f RecodedCharIDHash: Fix runtime errors detected by UndefinedBehaviorSanitizer 
Fix this runtime error in recodebeam_test and unicharcompress_test:

    src/ccutil/unicharcompress.h:84:27: runtime error:
      left shift of 267 by 28 places cannot be represented in type 'int'

code has up to kMaxCodeLen (9) values, so the highest possible value for
i is 8, and the shift value can reach 7 * 8 = 56.

That requires an uint64_t data type.
size_t would fit for 64 bit hosts, but be too small for 32 bit hosts.

028fff6edd classify: Use fixed size bit vector 
The vector was already limited to MAX_NUM_PROTOS (512) entries or 64 bytes
in the old code. Now it uses that size right from the start which avoids
reallocating it later when entries are added.

The old code which reallocated the vector to expand it was buggy because
the realloc function can return a different pointer, but the code still
used the original pointer to reset the new bits.

Function ExpandBitVector is now unused and therefore removed.

201ba0dd53 Fix handling of single pages from multipage TIFF files (issue #2537) 
That case now uses Leptonica to deliver the desired image instead of
using an inefficient loop in the Tesseract code.

See commit 54fafc4e2e which used similar
code in the past.
