ocs v2 endpoint still returns ocs v1 status codes

[individual-it]

compare results of ocs/v1.php and ocs/v2.php endpoint
e.g. curl http://localhost:9140/ocs/v1.php/config -u user0:123456 | xmllint --format -

both endpoints return

 <meta>
    <status>ok</status>
    <statuscode>100</statuscode>
    <message>OK</message>
  </meta>

but the v2 endpoint should return status-code 200 that is the same as the HTTP status code

[individual-it]

when trying to access the users endpoint with an authenticated user but one that is different to the one that is requested e.g. http://localhost:9140/ocs/v1.php/cloud/users/user1 -u user0:123456 its opposite, the OCS status code is 403 in both cases but the HTTP status code is 200

[individual-it]

not existing endpoints but with an authorised user return HTTP 200 and OCS 998 on both v1.php and v2.php

@C0rby I see you fixed part of it in cs3org/reva#696

what's left to do ? a checkbox list might be useful

Those are the last tests that still need some work.
