Besides, "sam" is Samaritan Aramaic, not Southern Sami

Changes for PHP 7.

No need to disable the error handler momentarily when guessing the timezone from the OS. Mask errors instead.

Fix a couple formatting issues in SimpleSAML\Utils\HTTP. Start using SimpleSAML\Module and SimpleSAML\Logger in there.

Fix build for older PHP versions that don't allow passing return values as a reference to a function.

Bugfix: there's a couple of places in SimpleSAML\Utils\HTTP where we should use the host AND port if the latter is not the default one, but we are only using the host. These are the case for evaluating the 'trusted.url.domains' configuration options (we should allow the host and port we are reachable in, but not other ports in the same host) and the method that returns the host with path, which should include the port if that's not standard (the documentation of the method already says so).

* bug/issue337:
  Rename Utils\HTTP::getSelfHostWithoutPort() to Utils\HTTP::getSelfHostWithNonStandardPort(), change the logic, and reimplement Utils\HTTP::getSelfHost() to depend on use the former. Complete the tests to include the case of port 443 while using HTTPS.
  Fixes issue 337

Add attribute mappings for eduPersonUniqueId

Another bugfix: sometimes, very early during execution, a class with namespaces might not be autoloaded yet, and if we are asked to load the old class without namespaces, it will fail. Make it load the file corresponding to the class first, and see if it exists then. If not, try to see if it has been migrated to namespaces, and create the alias then.

Bugfix: don't try to log anything before creating a class alias, as the logger itself might be subject to an alias.

Several updates to the Radius module
