This requires libarchive-dev.
Tesseract can now load traineddata files in any of the archive formats
which are supported by libarchive. Example of a zipped BagIt archive:
$ unzip -l /usr/local/share/tessdata/zip.traineddata
Archive: /usr/local/share/tessdata/zip.traineddata

`combine_tessdata -d` and `combine_tessdata -u` also work.
The traineddata files in the new format can be generated with
standard tools like zip or tar.
More work is needed for other training tools and big endian support.

The newer version contains fixes for the pixUnsharpMaskingGray*
functions which are relevant for Tesseract (used in ImageData::PreScale
which calls pixScale).

* Use container based Ubuntu trusty. This provides a newer gcc version
by default. CI jobs should now start faster.
* Add caching. Leptonica is now only built once for each platform.
* Get Leptonica tar instead of zip file. It's smaller,
and there is no need to store it on disk.

This command fails currently:
wget http://www.cmake.org/files/v3.3/cmake-3.3.1-Linux-x86_64.sh
Obviously cmake.org now redirects to https connections, so we have to
fix the URL. Then there still remains a certificate problem. Adding
--no-check-certificate is a workaround which should be removed later.
