#1153 mod_websocket: Expose original request object for use by modules
Description of feature:
Websocket sessions should expose their original request object. This may contain data that is useful to modules, such as request headers (including cookies) and connection details.
mod_bosh already does this, and currently it's impossible to make a module that supports both BOSH and Websocket connections (e.g. an auth module that reads a cookie), although both connection methods should be treated equally.
