* Replace log2(n) by faster local function
This also adds support for environments without a log2 function (Android).

* 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.

If equ_detect_ can be NULL, we must catch that case and show a warning
instead of crashing in method SetEquationDetect.

It looks like those files were added accidentally
in commit fc6a390c6c.
Add them to .gitignore to avoid that from now on.

* 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.

* 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.

Since commit cdc35338c5 Tesseract checks
the value passed for `--oem NUM`.
That only works as expected when the old (now unused) engine mode values
for cube are removed.

Fix it by using an unsigned index and use the same type for related values.

ftell returns a long value which can be negative when an error occurred.
It returns LONG_MAX for directories.
Both cases were not handled by the old code.

If unicharset_extractor was called without any argument,
a help message was printed by tesseract::ParseCommandLineFlags.
Replace that by the local help message which is better.

Now Tesseract adds a page break (normally form feed) by default.
It is still possible to suppress page breaks by setting an empty
page_separator.
