Updated subversion packages fix security vulnerabilities

Subversion’s mod_authz_svn does not properly restrict anonymous access in some mixed anonymous/authenticated environments when using Apache httpd 2.4. The result is that anonymous access may be possible to files for which only authenticated access should be possible (CVE-2015-3184). Subversion servers, both httpd and svnserve, will reveal some paths that should be hidden by path-based authz. When a node is copied from an unreadable location to a readable location the unreadable path may be revealed. This vulnerablity only reveals the path, it does not reveal the contents of the path (CVE-2015-3187). This update also re-enables the java subpackage for the Mageia 5 subversion package (mga#16075).
