Tests are failing, but it looks like compatibility issues with other ServiceManager v3.

As I said on #23,
Since PHP 5.4.0, <?= is always available.
Is this BC break ?
( situation when user uses extending \Zend\View\Stream ?)

@sasezaki the reason this is labeled as BC break is removal of API (even if protected). The correct approach could be deprecation + removal of these method bodies, while the API survives till the next major release.

@sasezaki it's an API change, which means that any subclasses may be broken by the change (that's why we use private by default now)
