27ce472666 Fix potential crash with --psm 0 and use osd.traineddata automatically 
Page segmentation mode "OSD only" requires osd.traineddata,
so use it automatically.

b19e69086c training: Add new flag --workspace_dir to tesstraining_utils.sh 
By default, that script creates two new temporary directories with random
names in /tmp.

The new command line flag --workspace_dir PATH uses the given path as
a base directory for all temporary files.

That allows better reproducable training results (no random directory
names in log files).

91c7504a35 Added a feature to enrich the hOCR output with glyph confidences 
By using the parameter -c glyph_confidences=true the user is able to enrich
the hOCR output with additional information. Tesseract then lists additionally
the timesteps with all glyphs that were considered with their confidence
for every timestep of the LSTM.

The format of the hOCR output is slightly changed: There is now a linebreak
after every word for better readability by humans.

b15624eb2f Fix regression (shared libraries no longer supported) 
The first usage of AC_CHECK_HEADERS must be unconditional,
otherwise configure fails to detect support for shared libraries.

This fixes a regression introduced by commit a07025c993.

Stefan Weil
f577e292c2 Increase limit and add assertions for deserialization of large arrays 
One of the checks was too restrictive, as lstmeval deserializes
char arrays with 14000000 elements, so raise the limit to 30000000.
That check was added in commit 992031e824.

Add also assertions which help finding such problems in debug mode.
