Add ObjectManager::isUninitializedObject()

[nicolas-grekas]

For 3.3

Adding ObjectManager::isUninitializedObject() will allow userland to decouple from the Proxy interface:

before:

if ($entity instanceof Proxy && !$entity->__isInitialized()) {
    $entity->__load();
}

after:

if ($em->isUninitializedObject($entity)) {
    $em->initializeObject($entity);
}

Also, I removed Proxy::__setInitialized() as I figured out it shouldn't be exposed as public API and it should remain an internal concern.

I don't think any API of doctrine/persistence uses the term Entity right now, which is a term used only by the ORM project but not by the ODM.

[stof]

should this be mixed or object ?

[nicolas-grekas]

it's mixed because this is commonly used against any values, eg in the UoW

[derrabus]

The object manager manages objects only, so object $object would indeed make sense here imho. It would also be consistent with all other methods on this interface.

[nicolas-grekas]

OK, renamed to isUninitializedObject then.

For 3.3

Wrong branch then?

The base branch was changed.

[nicolas-grekas]

I just created branch 3.3.x and changed the target of this PR. But I don't have permission to update the default branch on github.

[greg0ire]

Having the stable branch as the default branch is the policy for this repository AFAIK, having the next minor as default branch is a policy for the ODM, and maybe a few more, but not this one, so you did well.

Thanks @nicolas-grekas !
