* Provide local log2 function on platforms without log2 function

The existing implementation in wordrec/language_model.cpp is modified
to use a local inline function in the tesseract namespace and copied
to lstm/weightmatrix.cpp, too.

349de8b739 Support different help texts for normal and advanced users and restore legacy mode (#1325)
* Restore support for the legacy engine

It is still needed to get text attributes which are unsupported by the
LSTM engine, and it also has better recognition rates for some texts.

* tesseractmain: Add missing 'static' attributes

Signed-off-by: Stefan Weil <sw@weilnetz.de>

* Support different help texts for normal and advanced users

The old option --help now shows a very basic help text.
The new option --help-extra shows the full help information.
It now also includes a hint that Tesseract supports lists of images.

Fix also the indentation in the PSM help and
use a more neutral text in the OEM help.

c9169e5ac6 Remove unused cube OCR engine modes (#1281)
Since commit cdc35338c5 Tesseract checks
the value passed for `--oem NUM`.

That only works as expected when the old (now unused) engine mode values
