They are moved from src/classify and src/lstm to src/training.
This reduces the size of the Tesseract library.

The function pointers and callbacks file_reader_, file_writer_,
checkpointer_reader_ and checkpoint_writer_ are always set to
the same values. Replacing them by direct function calls
simplifies the code and allows removing more code from tesscallback.h.

C++17 drops support for `std::random_shuffle`, breaking C++17 compilers
that run to compile text2image.cpp. std::shuffle is valid on C++11
through C++17, so use std::shuffle instead.
Due to the use `std::random_shuffle`, `text2image --render_ngrams`
would not give consistent results for different compilers or platforms.
With the current change, the same random number generator is used for
all platforms and initialized to the same seed, so training output
should be consistent.
This fixes compiler warnings from clang++ like these ones:
src/ccutil/params.cpp:34:9: warning: macro is not used [-Wunused-macros]

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.
