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.
