Add tests for SimpleSAML\Locale\Language::getDefaultLanguage() and fix other tests for the same class.

Add more tests for SimpleSAML_Configuration::getDefaultEndpoint() and SimpleSAML\Utils\Config\Metadata::getDefaultEndpoint().

Make it possible to pre-load a configuration array into SimpleSAML_Configuration for subsequent calls to getInstance() to use it. This opens up for unit-testing code that calls SimpleSAML_Configuration::getInstance().

This used to work in old phpunit - but not the version on travis-ci

test core:AttributeLimit - since array can only contain int and string
I can’t raise the non covered constructor exception.

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

to a default value and then executing a test to change it.

Added some very basic tests for the AttributeAlter module.

Refactor SimpleSAML\Utils\Arrays::normalizeAttributesArray() to SimpleSAML\Utils\Attributes::normalizeAttributesArray().

Revert the new configuration option for the core:PHP authproc. Since we need to serialize authprocs and SP metadata in the state array, and closures are not serializable, it doesn't work. We could create a new module with this, adding a dependency on opis/closure 2.0.* or equivalent, to be able to serialize closures.

Refactor SimpleSAML_Auth_State::extractPersistentAuthState() to getPersistentAuthData() to avoid confusions around the behaviour of this method.

Move SimpleSAML_Auth_Default::extractPersistentAuthState() to SimpleSAML_Auth_State::extractPersistentAuthState() and deprecate the former.

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

Move the DatabaseTest to tests/lib/SimpleSAML/ where it belongs. Reformat code. Fix a few issues with phpdoc. Removed some unused variable. Use typed methos from SimpleSAML_Configuration instead of getValue().

Reimplement \SimpleSAML\Utils\Crypto::aesDecrypt() and \SimpleSAML\Utils\Crypto::aesEncrypt() to use openssl instead of mcrypt. This removes the direct dependency on mcrypt and closes #228.
