* Store the auth state in the session so we don't have to query it every
time.

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.

If we have a jailed storage we must also fix the internal path on copy.
Else we pass in the wrong path.
