Request approved state for disabled apps with ocsid

Use new updater URL + add unit tests

take share target into account when updating recipient etags

Increase timeout again

Our test execution is terribly slow and now also exceeds more than one hour on our CI system. This means that Scrutinizer fails hard on a lot of PRs such as https://github.com/owncloud/core/pull/17217#issuecomment-116252420

Uses the new updater url "https://updates.owncloud.com/server/"

Fix PHPDoc + Indentation

Add endpoint with list of OCS providers

Update license headers

This adds a OCS provider list at `ocs-provider/` to enable a somewhat autodiscovery of services.

In the moment it is not possible for applications to add own entries and it is basically hard-coded in the controller. I'm aware that this is not an optimal solution and I'm happy for any pragmatic input that won't pollute our public API too much. (and is not a big super hack, this is already hacky enough ;-))

That said, I'd consider it as a first step also feasible to go with this somewhat hard-coded list and see if this gets adopted...

If no array of arrays is submitted make sure we still keep $sharedUsers
and $sharedGroups as arrays so the rest of the code keeps functioning as
it should.
