hgweb: make parsedrequest part of wsgirequest...

hgweb: make parsedrequest part of wsgirequest This is kind of ugly. But an upcoming commit will teach parsedrequest about the input stream. Because the input stream is global state and can't be accessed without side-effects, we need to take actions to ensure that multiple consumers don't read from it independently. The easiest way to do this is for one object to hold a reference to both items having access to the input stream so that when a copy is made, we can remove the attribute from the other instance. So we create our parsed request instance from the wsgirequest constructor and hold a reference to it there. This is better than our new type holding a reference to wsgirequest because all the code for managing access will be temporary and we shouldn't pollute parsedrequest with this ugly history.
