right after the merge of 4.14 release branch
+ manual fix on one line in:
* Arrangement_on_surface_2/include/CGAL/IO/Arr_text_formatter.h
* .travis/generate_travis.sh
Freie Universitaet Berlin (Germany), Martin-Luther-University Halle-Wittenberg
(Germany) and RISC Linz (Austria) as they transfer the copyright to other
sites.
and pollution of the global scope.
(it remains the fact that it's non sense to have a static variable in a header file,
but it's only debug code, so...)
* CGAL_error to CGAL_error_msg
* introduced a macro CGAL_error()
* added some words about CGAL_error to the developers manual
* renamed most of assert(x) into CGAL_assertion(x)
* renamed exit(x) with x != 0 , CGAL_assertion(false) and assert(false) into CGAL_error
* CORE left untouched, OpenNL changed
