In line with the previous commit, we now allow hooking in the exception handler, so that a module can implement its own logic to deal with certain exceptions.

Start using the new configuration exceptions, handling error situations that before led to blank pages or even worse.

Move the error-reporting logic in SimpleSAML_Utilities to the SimpleSAML_Logger class, and add a new method there to evaluate whether an error would be masked or not according to its level.

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

INCPREFIX has been added in March 2008 and was already deprecated in June 2008, i.e. > 7 years ago.

Moved logic pertaining to finding configdir to central location, added ability to set via environment variable

Move SimpleSAML_Utilities::initTimezone() to SimpleSAML\Utils\Time::initTimezone(). Deprecate the former.

Deprecate SimpleSAML_Utilities::disanleXMLEntityLoader(). Since we are requiring PHP 5.3, we can call libxml_disable_entity_loader() directly.

To prevent local and remote file inclusion attacks. This is in most cases
already disabled by default in system libraries, so this will be a no-op to
most systems, but to be safe we explicitly disable it also.

Fixes #74

This is necessary to make sure that if a minimum PHP error level
has been set, this is also respected by SSP's error handler. Most
notably, this will make calls prefixed with '@', the PHP warning
silencer, actually silence the warnings. The SSP code tries to
makes use of the @ sign on various places around the code, but
this will only work if it's actually checked here.

Due to a PHP bug combined with deprecation-warnings from the OpenID
library, we may fail with a fatal error due to not finding the
SimpleSAML_Logger class.

Enable the assertion handler for all pages which load www/_include.php.
This may lead to more logging of assertion failures, but should
otherwise be invisible.

This patch adds an exception handler which will catch all unhandled
exceptions and display an error page to the user. It also adds a
handler for PHP errors and warnings. This handler will show a stacktrace
of the error, and then pass the error to the normal PHP error handler.
