Any `\OCP\Authentication\IApacheBackend` previously had to implement `getLogoutAttribute` which returns a string.
This string is directly injected into the logout `<a>` tag, so returning something like `href="foo"` would result
in `<a href="foo">`.
This is rather error prone and also in Nextcloud 12 broken as the logout entry has been moved with
054e161eb5 inside the navigation manager where one cannot simply inject attributes.
Thus this feature is broken in Nextcloud 12 which effectively leads to the bug described at nextcloud/user_saml#112,
people cannot logout anymore when using SAML using SLO. Basically in case of SAML you have a SLO url which redirects
you to the IdP and properly logs you out there as well.
Instead of monkey patching the Navigation manager I decided to instead change `\OCP\Authentication\IApacheBackend` to
use `\OCP\Authentication\IApacheBackend::getLogoutUrl` instead where it can return a string with the appropriate logout
URL. Since this functionality is only prominently used in the SAML plugin. Any custom app would need a small change but
I'm not aware of any and there's simply no way to fix this properly otherwise.

PHP's json_encode only accept proper UTF-8 strings, loop over all
elements to ensure that they are properly UTF-8 compliant or convert
them manually.
Without this somebody passing an invalid User Agent may make json_encode
return false which will get logged as empty newline.

`\OC\User\Database::createUser` can throw a PHP exception in case the UID is longer than
permitted in the database. This is against it's PHPDocs and we should cast this to `false`,
so that the regular error handling triggers in.
The easiest way to reproduce is on MySQL:
1. Create user `aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa` in admin panel
2. Create user `aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa` in admin panel again
3. See SQL exception as error message

There was a setting to disable the last execution of cron. There is no known
problem with this write access and it was also questioned when this feature
was build in https://github.com/owncloud/core/pull/7689#issuecomment-38264707
Recently there was also a bug report about a non-visible last cron execution
(#6088) - let's better remove this.

If you set the permissions on a public share the SHARE permission makes
no sense. So instead of throwing a warning. Just filter out the share
permission.

If the share input field is unfocused, the autocomplete list is closed. Once
the field was focused again it was not properly opened again. This adds a
trigger to redo the search and show the results again.
