This looks for one of the header files which are included by Tesseract.
It currently uses a hard coded path which works for Debian / Ubuntu.
Simplify also the rules for linking Tensorflow.

It expects include files in /usr/include/tensorflow.
* Add configure option --with-tensorflow (disabled by default)
* Fix data type tensorflow::int64
* Remove "third_party/" in include statements
* Add dummy implementations for Backward and DebugWeights in TFNetwork
* Add files generated with protoc from tfnetwork.proto
(so the Tensorflow sources are not needed for the build)
* Update Makefiles

It is defined for all platforms when math.h or cmath is included
after defining the macro _USE_MATH_DEFINES.
Define _USE_MATH_DEFINES before any include statement to make sure
that M_PI gets defined. It is not necessary to define it conditionally
only for Windows.

Void functions should not use @return. It causes compiler warnings
like this one:
src/classify/intproto.cpp:326:5: warning:
'@return' command used in a comment that is attached to a function
returning void [-Wdocumentation]
Some non-void functions also were documented with @return none.
Fix those comments, too.

Remove unneeded include statements for host.h, add required ones and
update the comments for the remaining include statements.

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.
