0.8.4a - 0.8.5
This release introduces interface incompatibilities with 0.8.4.
An interface of Auth_Plugin_base has been changed. Now one must implement do_authenticate_anonymous instead of transfering flag to Auth_Plugin_base constructor.
* The fix allows one to stop server by calling Server::set_exit_flag fromanother thread. This fix should also allow run multiple HTTP servers in one process.
This change was inspired by Mikko Sarmanne's patch.
