Fix an issue with the SimpleSAML\Logger class that was still trying to fetch the track ID from the session when running from the command line, where there's obviously no session at all.

Migrate all the logging handlers to namespaces. Make SimpleSAML\Logger a bit more intelligent so that it allows using custom logging handlers. Now you just need to implement SimpleSAML\Logger\LogginghandlerInterface in a class, and set the 'logging.handler' option in the configuration file to a string with the full name of your class.

If we are invoked from the command line, log the messages to standard error, instead of ignoring them.

Since we allow now defering log messages while we are initializing logging, we no longer need to dump them to the error log.

Allow passing as a parameter the logging handler to use in SimpleSAML\Logger::createLoggingHandler().

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.

Prevent the SimpleSAML_Logger class from creating loops while trying to get the track ID from the session. It must now be set manually by calling SimpleSAML_Logger::setTrackID(). Also allow SimpleSAML_Memcache to differentiate between a key not found in memcache and a request to memcache failed. If all servers are down, an exception is thrown and the user informed about the internal error. This hopefully resolves #264.

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

Reformat the logging classes. Extract the LoggingHandler to its own file. Add proper documentation. Fix typos.

PHP on Windows does not differentiate between all the different log
levels, which means that attempting to specify the 'logging.level'
option will not work properly. This patch replaces the use of the
syslog constants with custom constants.

Thanks to Ryan Panning for fixing this bug!

Adding a SIMPLESAML_INCPREFIX parameter before the inclusion of new files. This workaround was neccessary for university of oslo to make simplesamlphp work when ini_Set was not available.

Improvement to debuglogging logging in general, handling of illegal input to saml interfaces, improved error handling, better language support, collected all error messages in one dictionary file. +++

renamed the logger class to follow the guidelines for classnaming. Also added some new log entries, and add an entry for SSO login statistics

TrackID is always prepended to the logstring

New logging options in config-template.php

Possible to configure logging to use syslog or file

Please test the new logging function. 

Logging handler has only been added. The old logging function is still uses in the code. 

After test all logging calls should be rewritten to the new format.

Usage:

Required:

require_once('SimpleSAML/Logger.php');

Logging:

Logger::emergency("text to log");
Logger::critical("text to log");
Logger::alert("text to log");
Logger::error("text to log");
Logger::warning("text to log");
Logger::notice("text to log");
Logger::info("text to log");
Logger::debug("text to log");
Logger::emergency("text to log");

Logger::info(array("text","to","log"));

Statistics:
Stats are prepended with STAT in the logfile for easier analysis.

Logger::stats("SSO");

Example (syslog): 
Feb  7 21:02:33 server_name simpleSAMLphp[pid]: [trackid] loglevel text to log

Added some more debug logging, and fixed a serious bug with the session clean() method that caused bridging to not work properly as the cached requestID also was cleaned :)

Implementeed better error handling. Separate static function for fatal error in utitilies that present a error the user. This page to the user shows a error text that can be localized to several languages, the error page also shows debug text, and a way to submit errors to the administrators.

Added the possibility for the logger to get the trackID it self... Temporary thing, we shuold rewrite and improve the logging class a bit.
