First version of new CalDav/CardDAV/GroupDAV access for calendar and addressbook (infolog will follow). CalDAV is tested so far with lightning 0.8 and Apple's iCal.

Backported r26747 to 1.6: using a session for basic auth (not session aware) clients for WebDAV and GroupDAV. The "sessionid" get's constructed from the basic auth credentials and is not random (as the clients dont store them). --> speeds up the use of DAV --> stops DAV handlers to created numerious sessions 2009-04-09 09:49:17 +02:00			`* @copyright (c) 2007-9 by Ralf Becker <RalfBecker-AT-outdoor-training.de>`

Improved exception handling: - exceptions get now always logged to the error_log - in the webgui it's now configurable, if the message contains a stacktrace (incl. function arguments) - default no (security) - command line interfaces get detected and contain no html anymore - webdav and groupdav send the exceptions as basic auth realms to the client - webdav and groupdav login failures contain the reason as part of the basic auth realm 2008-10-26 13:13:01 +01:00			`$starttime = microtime(true);`
