It's not very useful to log backtraces always as debug, since that implies getting all the log messages, while backtraces would still help debug a particular error.

The code was enforcing this option even if a configuration was passed as a parameter to the constructor. If there is something wrong with a configuration and we are passing it to the constructor, we should know if at least the 'baseurlpath' is correct, and if not, fix it somehow.

This bug was producing a default configuration without 'baseurlpath', when no configuration was passed. In that situation, only the default path (/simplesaml) was working correctly.

This way we can discern why we couldn't set a cookie, and act accordingly.

Add a couple new exceptions, both to signal configuration issues. One can be used to signal an error in a certain configuration, leaving to the user deciding whether it was critical or not, and what to do to deal with it. The other one indicates a configuration exception that we cannot recover from (i.e. missing files), and bootstraps a minimal configuration skeleton that we can use to go on momentarily.

Fix build. It was broken due to a chicken & egg problem, with SimpleSAML_Configuration raising creating a new SimpleSAML_Error_Exception that tries to load the configuration.

- Exception messages and backtraces are now decoupled, so that they can be logged independently.
- Backtraces are now logged with "debug" log level, and only in case the "debug" configuration option is set.
- A new log() method allows the exception itself to decide which log level to use. This can be used by exceptions overriding this method to change the log level accordingly.
- Add a new parameter to the format() method so that the formatted message is anonymized, safe for display in the browser.

Additionally, this resolves #281.

Add a proper message to the SimpleSAML_Error_NotFound exception, instead of printing its parameters.

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

Move SimpleSAML_Utilities::selfURLNoQuery() to SimpleSAML\Utils\HTTP::getSelfURLNoQuery() and deprecate the former.

Move SimpleSAML_Utilities::selfURL() to SimpleSAML\Utils\HTTP::getSelfURL() and deprecate the former.

Move SimpleSAML_Utilities:::getBaseURL() to SimpleSAML\Utils\HTTP::getBaseURL() and deprecate the former.

Stop calling SimpleSAML_Session::getAttributes() in SimpleSAML_Error_Error class. Use an alternate way to try to fetch user's mail.

Rename SimpleSAML_Session::getInstance() to SimpleSAML_Session::getSessionFromRequest(), and leave the former as deprecated.

This patch also changes the MetadataNotFound and NoState errors to use this structure.
