Fix this here in the source so it will propogate into the documentation.
Edit was already applied in https://github.com/owncloud/documentation/pull/2208 but needs to be done here at the source.

* if you install owncloud via package it is not
  possible to skip migration tests
* this also allows to disable migration tests for
  an instance by default

Added config.php option to replace the default implementation of system
tag manager and system tag object mapper.

Also adjusted the comments manager factory to inject the server container

* Add providers
* Add share manager to server container
* Use share manager from server container
* Properly get the share manager

I corrected the word order.

register CommentsManager service, allow override, document in config.sample.php

don't insert autoincrement ids in tests, because of dislikes from oracle and pgsql

specify timezone in null date

only accepts strings for ID parameter that can be converted to int

replace forgotten hardcoded IDs in tests

react on deleted users

react on file deletion

Postgresql compatibility

lastInsertId needs *PREFIX* with the table name

do not listen for file deletion, because it is not reliable (trashbin, external storages)

add runtime cache for comments

This changeset allows ownCloud to run with pretty URLs, they will be used if mod_rewrite and mod_env are available. This means basically that the `index.php` in the URL is not shown to the user anymore.

Also the not deprecated functions to generate URLs have been modified to support this behaviour, old functions such as `filePath` will still behave as before for compatibility reasons.

Examples:
http://localhost/owncloud/index.php/s/AIDyKbxiRZWAAjP => http://localhost/owncloud/s/AIDyKbxiRZWAAjP
http://localhost/owncloud/index.php/apps/files/ => http://localhost/owncloud/apps/files/

Due to the way our CSS and JS is structured the .htaccess uses some hacks for the final result but could be worse... And I was just annoyed by all that users crying for the removal of `index.php` ;-)

For enhanced security it is recommended to configure Redis to only accept connections with a password. (http://redis.io/topics/security)

This is especially critical since Redis supports the LUA scripting language and thus a simple SSRF vulnerability (as proven in http://benmmurphy.github.io/blog/2015/06/04/redis-eval-lua-sandbox-escape/ for example) may lead to a remote code execution.

This reverts commit 7cbdd9b9.

* ref #16891

* migrate DEBUG constant to config value
