DB scheme for Comments table, resolves #20265

webdav docker tests - wait at least 5 seconds after the full startup

Requested sharing API test cases.

Do not authenticate over ajax Webdav

p() supports string as argument

lastInsertId() is properly working with Oracle if the table name is p…

Move hook and delete children logic to share manager

Use a DateTime object instead of a timestamp

To make sure hooks are always fired and child entries are always
cleaned. This logic is moved to the share manager.

* Updated unit tests

federated sharing auto-complete, first step

Add cmdline key to show shipped/non-shipped apps only

This makes sure that whenever a Webdav call is done through Ajax, if the
session has expired, it will not send back a challenge but a simple 401
response. Without this fix, the default code would send back a challenge
and trigger the browser's basic auth dialog.

Web UI uses Webdav instead of ajax/* calls

assume pgsql >=9 if checking the version fails

Unset `path` for shared with me

[Settings] Moved changedisplayname to usercontroller

Scrutinizer Auto-Fixes

[3rdparty] Bump for symfony/console-2.7.4

This will make sure the cached JS gets properly updated.
Also, since this is a bigger change it also qualifies for a version
increase :-)

This used to be done in the ajax download code. Now that single file
downloads are going through Webdav, the token handling needs to be done
here too.

This prevents double slashes that can mess up path comparisons in some
cases.

This makes it possible to also store custom properties passed through
the data object like tags or shareOwner.
