*
* This function removes the bidi and boundary-neutral marks out of an string

* Bidirectional Algorithm available at
* http://www.unicode.org/reports/tr9/#X9, with the exception that it removes
* U+200E LEFT-TO-RIGHT MARK and U+200F RIGHT-TO-LEFT MARK too.
*
* If any of the input lists are NULL, the list is skipped. If str is the
* visual string, then positions_to_this is positions_L_to_V and
* position_from_this_list is positions_V_to_L; if str is the logical
* string, the other way. Moreover, the position maps should be filled with
* valid entries.
*
* A position map pointing to a removed character is filled with \-1. By the
* way, you should not use embedding_levels if str is visual string.
*
* For best results this function should be run on a whole paragraph, not
* lines; but feel free to do otherwise if you know what you are doing.
* Deprecated. Use fribidi_remove_special_chars instead.
*
* Returns: New length of the string, or \-1 if an error occurred (memory
* allocation failure most probably).
