Refactor SimpleSAML_XHTML_IdPDisco::filter() to filterList(), and extend in sspmod_discopower_PowerIdPDisco.

Reformat the PHP authproc filter. Add a new 'function' option that allows to define an anonymous function. Deprecated the old 'code' function. Add tests.

Allow to specify which metadata sets to use in metarefresh. Can be configured either per set or per source.

SimpleSAMLphp no longer requires mcrypt, it will only be needed depending on the configuration, so mark it as optional.

No data about previous authentication is stored if authentication was not started at the SP (IdP-first flow). That makes the replay protection measures fail, leading to an ugly exception show to the user. Fix that.

Additionally, give precedence to the RelayState configured in the local metadata, as the one received together with the SAML response may not even be an URL.

This resolves #230.

$t - not grep-safe, used in 3rd party libs for other things
$template - only used for templates last I checked

Useful in the leadup to entity category support to publish
registrationAuthority (which might be overridden by a federation) and
attributes.required.

uid and organization attributes are not always in `$creds['attributes']`, so we add an option for that.

It has been marked deprecated and generates warnings since 2013.
The functionality is easily replaced by using the smartattributes module.

Since PHP 5.3 is required, there's no need to treat users of 5.1.2-5.2 specially. Also we can safely use LDAP_OPT_NETWORK_TIMEOUT now.

It has never really gained traction and is now superseeded by the composer module installer.

This class has been broken for several years, and we are not aware of
any users of it. Delete that class and any code instantiating that class.

this admins array is not used anywhere,
but it may be misleading to administrators who wants to restrict
the access to the metadata registry.
