* One test suite for all tests.
* One file per class that is tested.

These changes should make it easier to add new tests.

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.

Update IPv6 CIDR checks.

This add testing on PHP 7.0 (nightly build). The test is added as an
allowed failure for now. but it can be useful to keep an eye on it just
in case we do something that won't work in PHP 7.

inet_pton failure is captured later - silence so unit tests pass.

Currently, if we try to load a class from a module, and the config.php
is absent, we will get an error about the missing configuration file.

There is no reason for the configuration file to be mandatory here,
since we have reasonable fallbacks, so fix the code to make it
optional.

This should make it easier to write tests for code in modules.

Add support for sender-vouches

Removed a 'if' sentence than prevents a Store class couldn't be added if it is named with a namespace instead with the sspmod_<module>_Store_<class> way.

Minor documentation corrections

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

Use InvalidArgumentException instead of SimpleSAML_Error_Exception when dealing with wrong input parameters.

Move validateCA(), validateCABuiltIn() and validateCAExec() from SimpleSAML_Utilities to SimpleSAML_XML_Validator, where they are used. Remove validateCABuiltIn() and validateCAExec() from SimpleSAML_Utilities as they are no longer used. Eventually, all of this should disappear.

Deprecate SimpleSAML_Utilities::maskErrors() and SimpleSAML_Utilities::popErrorMask(). These two should be where they are used, in the OpenID modules.

Move SimpleSAML_Utilities::resolveCert() to SimpleSAML\Utils\Config::getCertPath() and deprecate the former.

Move SimpleSAML_Utilities::parseStateID() to SimpleSAML_Auth_State::parseStateID() and deprecate the former.
