This enables "make test" in every extension and eases the test of changes to PHP. I did ignore PHP 7.0 intentionally since it only receives security updates and will EOL at the end of the year. Therefore no great amount of work is expected for 7.0.
Notable changes: - mcrypt module was removed - sodium module was added - sybase_ct artifacts removed Also many PECL ports will not work with this version since some files got renamed.
