let init() take a ICollection or an INode - fixes PHP message

Indicate that the share owner is remote in the filelist

Prevent wrapping null storage

Catch storage exception in scanner for remote shares

Can happen when trying to instantiate external storages that have
incomplete config, where the constructor throws an exception (the
exception is caught in createStorage())

Use proper namespace

IAppManager lives in OCP\App and not in OCP.

Fixes https://github.com/owncloud/core/issues/13710

Call final unlink in trash wrapper's storage

Allow saving incomplete external storage config

Use `file_exists` to verify that config file exists

Add value if restore of data is possible for a user

This is needed for Dropbox and others that need a token.

Because setStorageId now instantiates storages, they might throw
exceptions if arguments are missing.

This fixes the unit test to not throw exceptions and have their default
config arguments set.

* reason: nice to know before password change in user management
* restore is possible:
	* encryption is disabled
	* encryption is enabled, admin and user has checked the
	  restore option
* if not possible:
	* highlight users row in red once the admin wants to change the password
	* show also a little tipsy

Fix node interface

Disable JS plugin for sharing in public mode

Only reload file list after remote share accept request returns

disable the app code checker - some previous shipped apps cannot be installed from the appstore now :facepunch:

Make error more descriptive

There might be the case that `fopen($file, 'r')` returns false and thus ownCloud might believe that the config file is empty and thus potentially leading to an overwrite of the config file.

This changeset introduces `file_exists` again which was used in ownCloud 5 where no such problems where reported and should not be affected by such problems.

When accepting a remote share, an ajax request is sent to the server.
Only once this request returns should the file list be reloaded.

This removes the logic that registers the share action and modifies the
rows. Share actions aren't needed in the public file list.

use uid provided by setupfs hook to mount server2server shares

Prevent double slash in shareinfo request URL

certificate manager should always use a \OC\Files\View otherwise we will get problems for different primary storages

use uid provided by setupfs hook to mount server2server shares, otherwise mount will fail for public link shares

Remove duplicated definition of APIController
