PSR-12 compliancy

* Ensure getConfig* functions can only return Configuration

* Cleanup after #1189

* Deprecate Configuration::getConfigList

Pass an instance of SimpleSAML\Configuration and SimpleSAML\Session as optional parameters to SimpleSAML\Auth\Simple.

This allows us to inject both as dependencies of the class.

This reverts commit ef36c5fd.

All a bit too involved right before a planned release.

Also, convert to PSR-2 where that was still lacking in these files.

This method allows us to parse a URL and "rebase" it based on the $config['application']['baseURL'] configuration option. Thanks to this, applications will be able to configure a canonical base URL for the application, effectively translating any URL that might be built incorrectly (e.g. not using HTTPS because that is offloaded to a reverse proxy).

It can now be used with \SimpleSAML\Auth\Simple, although the old name still works too.

If we are asked to load an unknown auth source, we should raise a SimpleSAML_Error_AuthSource exception.

(being respectful with occurences that might change the behaviour, i.e. default database prefixes)

Throw an exception in SimpleSAML_Auth_Simple when the auth source cannot be found. This avoids trying to access a method in an object that's actually null.

Deprecate SimpleSAML_Default::initLogin() and move it to SimpleSAML_Auth_Source as a non-static method.

Move SimpleSAML_Utilities:: redirectTrustedURL() to SimpleSAML\Utils\HTTP:: redirectTrustedURL() and deprecate the former.

Move the createPostRedirectLink(), postRedirect() and createHttpPostRedirectLink() methods in SimpleSAML_Utilities to \SimpleSAML\Utils\HTTP. The last one is made private, the others are renamed to submitPOSTData() and getPOSTRedirectURL(), respectively. Deprecate the three old ones.
