Without /dev/urandom being available to read the medium RNG will rely only on the following components on a Linux system:
1. MicroTime: microtime() . memory_get_usage() as seed and then a garbage collected microtime for loop
2. MTRand: chr((mt_rand() ^ mt_rand()) % 256)
3. Rand: chr((rand() ^ rand()) % 256)
4. UniqId: Plain uniqid()
An adversary with the possibility to predict the seed used by the PHP process may thus be able to predict future tokens which is an unwanted behaviour.
One should note that this behaviour is documented in our documentation to ensure that users get aware of this even without reading our documentation this will add a post setup check to the administrative interface.
Thanks to David Black from d1b.org for bringing this again to our attention.
Replaces the OC_Mail and phpmailer with SwiftMail allowing us to mock it properly.

Doing this in the PHP code is not the right approach for multiple reasons:
1. A bug in the PHP code prevents them from being added to the response.
2. They are only added when something is served via PHP and not in other cases (that makes for example the newest IE UXSS which is not yet patched by Microsoft exploitable on ownCloud)
3. Some headers such as the Strict-Transport-Security might require custom modifications by administrators. This was not possible before and lead to buggy situations.
This pull request moves those headers out of the PHP code and adds a security check to the admin settings performed via JS.
* 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
add logSettingsController
add download logfile button
move getEntries to LogSettingsController
move set log level to logsettingscontroller.php
add warning if logfile is bigger than 100MB
add unit test for set log level
fix typecasting, add new line at EoF
show log and logfile download only if log_type is set to owncloud
add unit test for getFilenameForDownload
* introduced new route settings/users/{id}/mailAddress
* kept old responses
* better error messages
* dropped lostpassword.php from settings/ajax
* cleaned up the UserList.add() and hand in user object instead of
each attribute as another parameter
* check for change permission of mail address
* proper response messages
* add switch to settings to show user backend
* user classes for headers and rows to unify the show/hide statement
* add user backend to response of user create request
* proper markup in settings area
This adds a "backend" type filter to the index REST route which is a pre-requisite for https://github.com/owncloud/core/issues/12620
For example when calling `index.php/settings/users/users?offset=0&limit=10&gid=&pattern=&backend=OC_User_Database` only users within the backend `OC_User_Database` would be shown. (requires sending a CSRF token as well)
Depends upon https://github.com/owncloud/core/pull/12711
This change will expose the user backend via the REST API which is a pre-requisite for https://github.com/owncloud/core/issues/12620.
For example:
````json

```
First step of a somewhat testable user management. - I know, the JSON returns are in an ugly format but the JS expects it that way. So let's keep it that way until we have time to fix the JS in the future.
This patch wil warn the user of the consequences when resetting the password and requires checking a checkbox (as we had in the past) to reset a password.
Furthermore I updated the code to use our new classes and added some unit tests for it 👯
Fixes https://github.com/owncloud/core/issues/11438
